Unity is visible on top of fullscreen apps

[Federico Raimondo]

[Test Case]
1. Start a fullscreen application (e.g. Firefox in Fullscreen mode)
   -> Verify that the panel is not visible

[Regression Potential]
Visual regressions, shell drawing problems. Part of a big change, many regression potentials.

Original description:

NOTE: This bug is only about the single monitor case. If you still have problems with multiple monitors, see bug 748539 instead.

ORIGINAL DESCRIPTION:
In natty alpha 3 up to date, I cannot get fullscreen in any application. Panels are still visible.

Tested with:
- totem
- vlc
- firefox
- chrome
- geany

Unity panel and top bar are always on top.

-----------------------------------------------------
Desired Solution:

- When a window is fullscreen (note: this should not be confused with the *maximised* state) the menu bar should not be displayed.

I'm attaching 4 images:
- Chrome
- Evince
- Firefox
- VLC

[Federico Raimondo (fraimondo)]

Tried again on another natty updated pc.

Apparently, the problem is seen when a multi screen setup is being used.

Steps to reproduce:
1) With only one display configured, open a PDF file with evince. Press F11. Fullscreen works correctly.
2) Plug in a second display (tested with HDMI out on notebook and DVI on desktop pc)
3) Configure twinview (both pcs have nvidia cards)
4) Open a PDF file with evince in the main display (the one that has both panels). Press F11. Panels don't hide.

[Kieran Hogg (xerosis)]

I can confirm this happens for me for example when full-screening totem to watch a video. I have dual-screen but don't have to connect the monitor afterwards to reproduce.

[Federico Raimondo (fraimondo)]

Screensaver is below panels too.

I'm currently presenting a pdf with pdf-presenter. The panels are visible in fullscreen.

I went away for a while, the screen was black with both panel visibles. I pressed a key and entered my password to unlock. Both bars were visible. Nevertheless, when I click nothing happens untill I enter my password. It's not a security issue, but it is anoying.

[Ben Straton (fanum)]

Occurring for me with a single monitor set up. Let me know what information you need to help resolve this.

[Omer Akram (om26er)]

This bug report is specific to multimonitor setup. If you face a similar bug with single monitor setup please report a new bugs with the steps to reproduce the issue.

It happens too but with a single monitor https://bugs.launchpad.net/ubuntu/+source/unity/+bug/792690

[Eduardo Rivas (jerivasmelgar)]

Oneiric is out and this is still an issue.

[Sam Spilsbury (smspillaz)]

Can't reproduce - the panels always go under fullscreen windows here.

[Sam Spilsbury (smspillaz)]

(this is with multimonitor)

[Kieran Hogg (xerosis)]

I'm sure I, or others, can get you a screencast of this bug occuring, therefore marking it invalid is not the correct solution.

[Alex Burdu (alex.burdu)]

this bug is not invalid. i am affected by it too

[Kieran Hogg (xerosis)]

My latest annoyance with this bug is running full screen virtual machines, see screenshot.

[Kieran Hogg (xerosis)]

The same root cause is now quite obvious with the addition of two panels in Unity 5.2 as not only is the menu bar appearing over full screen apps, the launcher is too :(

[Maximilian Federle (ppd)]

I'm experiencing a very similar bug. The whole unity stuff (launcher + panel) is visible over fullscreen windows.
However this is ONLY when the fullscreen window looses focus.
This may happen when you click on the second monitor or somehow activate a window on that monitor.

So are we maybe talking about the same?
Please pay attention to whether the panel appears over the window before or after the fullscreen window loses focus.

That is a huge difference and should be made clear in the bug description.

[KarlRelton (karllinuxtest-relton)]

With reference to comment #42, the issue described in that comment matches the problem I reported in
https://bugs.launchpad.net/unity/+bug/907464 which is now marked as a duplicate of this bug.

The two bugs are obviously related, but not necessarily exact duplicates, at least in my view.

[quequotion (quequotion)]

This is not limited to multimonitor.

I have been having this issue with a single monitor for as long as I've been using Unity.

There's an interesting blog post here:

http://somethingididnotknow.wordpress.com/2012/02/09/set-fullscreen-windows-to-go-over-gnome-shells-and-unitys-top-bar-with-python-and-glade/

Which suggests that fullscreen() may not be enough, and that only windows with window-type "Popup" can cover panels in gtk3.

[Aaron Roydhouse (aaron-roydhouse)]

I see this too. Unually the window goes full screen initially, but later while you are using the full-screen app, the Unity stuff pops on top of the full-screen app. I get it most when using Bibble 5 / AfterShot Pro and I think it may be related to when focus changes to a pop-up window the full screen app pops-up. I get this when using a single-screen, mainly because that is where I use apps full-screen.

[quequotion (quequotion)]

What does it mean when a fix is committed to ayatana design?

[Daniel van Vugt (vanvugt)]

This is not just a multimonitor issue, as demonstrated by some duplicates.

[quequotion (quequotion)]

On a single monitor desktop, I've found this problem more prevalent with Unity+Cube than Unity+Wall desktops.

Unity+Wall usually does not show the panel while a window is in full-screen.

Unity+Cube almost always shows the panel on top of all fullscreen windows.

Also, I noticed another potential communication problem:

"on top" (3d) meaning "layered on top" looking down the z axis. this could also be said as "in front"
"on top" (2D) meaning "located at the top of the screen" on the x axis. the unity panel resides at the top of the screen.

The panel is visible "on top" (3d) of fullscreen windows.

With a fully transparent panel, you can see the fullscreen window content "under", or "behind", the appmenu/indicators/clock/etc.

[Daniel van Vugt (vanvugt)]

Hey all, please note:

If unity still responds to the mouse when it's overdrawing a fullscreen app, then that means this is a compiz stacking bug.

If unity does not respond to the mouse and clicks go directly to the fullscreen window below, then it's just a rendering bug in unity. In that case, this upcoming fix should resolve it:
https://code.launchpad.net/~vanvugt/unity/regionalDamage/+merge/109809

[Greg A (etulfetulf)]

I am seeing a different bug to the one Daniel refers to. (Unity does respond to mouse clicks).

Therefore, for the multimonitor case I've reopened Bug #748539 and included steps to reproduce.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[keepitsimpleengr (keepitsimpleengineer)]

Surely this is being worked on...

...every time I demo Mythtv, they invariably ask "what's that on top of the tv screen?"

[MC Return (mc-return)]

Daniel, bug 748539 describes the problem and reproduction of it perfectly.
It seems to be a Compiz stacking bug that is involved here also, because the Unity panel is still responsive.
Bug 748539 is still valid on Ubuntu 12.10, Compiz 0.9.8 + bzr3249-0ubuntu2, Unity 5.12+bzr2462ubuntu0+718.

[Daniel van Vugt (vanvugt)]

Fix committed into lp:unity at revision 2470

[Daniel van Vugt (vanvugt)]

Bug 748539 is a different case (for unity) and no longer a duplicate. I suggest the duplicates of this bug need to be re-reviewed to see if they are instead duplicates of bug 748539.

That all said, Sam's compiz fix for *this* bug might also fix bug 748539.

[quequotion (quequotion)]

>>Didier

Really? Where?

[Daniel van Vugt (vanvugt)]

quequotion:

Fix released in "unity", meaning source code 6.0 released:
https://launchpad.net/unity/+milestone/6.0

Packaging for Ubuntu 12.10 is coming soon. And if all goes well, then it will be back-ported to 12.04 after that.

Normally you should watch for "unity (Ubuntu)" to know when a fix hits Ubuntu, however it was marked Fix Committed by Omer a little early. Apparently that's standard practice for Unity bugs (?).

[quequotion (quequotion)]

>>Daniel

I see.

I thought "Fix Released" was intended to mean a working binary was available either in PPA or a main repository.

I did find unity 6.0 in quantal today, and--being eager to be rid of this bug--decided to give it a shot...

The procedure was not easy, as I do not intend to upgrade to quantal at this time or add it's repositories alongside precise, and involved manually resolving an convoluted dependency chain.
Luckily, this is something I have done before (downgrading xorg, upgrading compiz, etc.)

As far dpkg is concerned, and as far as I can tell, I now have a complete installation of unity, compiz, nux, etc. from quantal inside precise.

Unity is blinking in and out of existence almost constantly.

The panel, launcher, lenses and scopes are all in constant flux...

I am not sure that there's anything standard about unity or it's bugs.

[Daniel van Vugt (vanvugt)]

quequotion: That blinking problem is specific to precise as far as I know. It does not happen on quantal (AFAIK) with compiz 0.9.8 and nux 3.0, which is the target platform right now.

I will be investigating the blinking on precise later, as part of the back-port to precise.

Also, I gave the "Show Repaint" plugin a try for the first time ever today.

I don't know if this is normal or could be related to the bug, but the plugin indicates continuous, periodic (in 1 to 4 second intervals) repaints when nothing is happening on the screen (no cursors, no animations, no videos, mouse not moving, etc).
The clock would need redrawing every minute at least, but I'm not sure what else might be redrawing.

[quequotion (quequotion)]

I forgot to say:

During some of those periodic repaints unity is momentarily visible, but for the majority of them it is not.

[MC Return (mc-return)]

Daniel, I am not able to confirm this fix yet.
Using compiz 1:0.9.8-1+bzr3285-staging1-201207130249~quantal1 the panel is still visible on top of fullscreen applications.

When setting a video to run fullscreen on my second monitor (1280x1024) the Unity-panel disappears first, but once I click on any other window on my main monitor, the Unity-panel on the second monitor instantly reappears. Clicking on the running fullscreen video makes this panel disappear again.

Trying to set the same video to fullscreen on the main monitor (1920x1200) presents me a completely black screen plus a (hiding) mousecursor now :( - there is no Unity-panel visible or appearing on the main monitor, even if I select another window on the second screen.

[Daniel van Vugt (vanvugt)]

mc-return, that is bug 748539, which is a different multi-monitor case that is not yet fixed.

[MC Return (mc-return)]

Daniel, sorry then.

If you are using Mythtv, and this bug is affecting you, switching to Unity 2D will provide a workaround.

[quequotion (quequotion)]

>>Daniel

I found a clue about the blinking with unity 6.0, nux 3.0, and compiz 0.9.8 in Precise

First, I tried making a new user to see if the desktop was affected.
It wasn't, but I noticed another problem: windows cannot full-screen.
I tested firefox (f11) and totem (double click or f11).
Both applications freeze the current viewport and will not enter full-screen, but can be recovered by exiting full-screen.

Next, I started crawling through ccsm, trying each and every button.
In Desktop Cube -> Transparent Cube -> Opacity When Not Rotating:
The default value is 100%, at which Unity stops blinking and windows cannot full-screen.
At any value less than 100%, Unity will start blinking and windows can full-screen.

So, there's a connection between the blinking, cube opacity, and full-screen.

Any idea what it might be?

Maybe this needs a new bug report.

[Daniel van Vugt (vanvugt)]

quequotion, those are known issues. Please discuss them in the appropriate bugs:

Full screen freeze --> bug 1024911
Blinking unity --> bug 1024459

[quequotion (quequotion)]

>>Daniel

Thank you for the references.

I will comment on both, but neither issue is quite what I'm experiencing.

I altered the opacity setting for the desktop cube, not the panel.
When the cube is opaque, then panel stops blinking and windows can full-screen.
If the cube is less than opaque, the panel blinks and windows cannot full-screen.

Changing the panel's opacity had no effect.

All of unity (panel, launcher, dash, hud) is blinking when any window is open, not only libreoffice.

[quequotion (quequotion)]

mistype!!

that should say:

When the cube is opaque, then panel stops blinking and windows CANNOT full-screen.
If the cube is less than opaque, the panel blinks and windows CAN full-screen.

[Daniel van Vugt (vanvugt)]

quequotion:

Please log your issues as new bugs. And please be aware that if you're running unity 6.x on precise then that is not supported so you're unlikely to get help with such bugs.

[quequotion (quequotion)]

Good news:
It's now completely irrelevant to file a bug report on the problems I had with unity 6.0.0-0ubuntu1.
The patches that fixed the other bugs also fix mine, so unity 6.0.0-0ubuntu2 looks ok.

Bad news:
The original bug, this bug, is not fixed.
The unity panel is still visible over all full-screen applications.

Clicks pass through to the fullscreen window, so it's the same compiz layering problem as before.

[quequotion (quequotion)]

*so it's the same unity rendering problem as before.

Maybe I'm suffering from bug 861710 as well?

[Daniel van Vugt (vanvugt)]

quequotion: Could you please upload information about your system using this command?...
    ubuntu-bug unity

That will log a new bug, which is likely to become a duplicate of this one. But it's better than filling this bug with apport data.

[quequotion (quequotion)]

>>Daniel

bug 1025535 is ready for review; your assistance is much appreciated!

[quequotion (quequotion)]

Can anyone provide screenshots showing that this bug has been fixed?

Specifically, I need to see:

- firefox in full-screen with no icons, clock, window title, etc
- a video playing in full-screen (any player) with no icons, clock, window title, etc.
- a game being played in full-screen with no icons, clock, window title, etc.
- a screensaver with no icons, clock, window title, etc.

I have not seen that the bug was fixed in any version of unity and I'd like to know if it's just me.

[quequotion (quequotion)]

Furthermore, has anyone else tested this issue against the desktop cube?

I am fairly certain the issue is still affecting the compiz cube.

Could you give a few more details about your desktops?

In particular, I'd like to know:

Have you changed any settings in CCSM? (i have this issue with "desktop cube")

What hardware & drivers do you use? (probably unrelated, but one never knows)

How many monitors do you use? (there's another bug report for multi-monitor)

[František Zatloukal (zatloukal-frantisek)]

Yes, that problem affects 2 of 2 my desktops :D
I don't use CCSM.
I use only one monitor.
First desktop - Intel Atom N455 + GMA 3150 - 1024 * 600
Second desktop - Amd Athlon QL 65 + Ati Mobility Radeon 4570 - free graphic driver - 1366 * 768

I don't use any ppa affecting xorg, mesa and drivers. On first desktop i've tried both - SNA & UXA backend - result is identical.
And last note - on both desktops i am using wine 1.5.10 from official ppa.

[Daniel van Vugt (vanvugt)]

All,

If you still have problems similar to this bug with a SINGLE monitor, then please run:
    ubuntu-bug unity
To ensure a new bug is created for us to track.

For multiple monitors, see bug 907464.

[Anders L. (vithiri)]

I must confess that I haven't read through the full history of this bug report, but I can confirm that it is still present in 12.04.1.

This happens when the full screen application on the second display is not focused.

As long as the application still has focus, the top bar (and the rest of the Unity interface if you have opted to show it) will remain hidden, but when the application loses focus it is drawn on top of everything on the display.

This is especially noticeable if you are running a presentation on the second display and need to keep another window focused on your main display, or if you (as in my case) are running a video on a connected TV set while using the computer for general browsing and bug reporting.

[František Zatloukal (zatloukal-frantisek)]

I've reported https://bugs.launchpad.net/ubuntu/+source/unity/+bug/1039045 .
Somebody should look at it - it is really annoying bug :/

[Matthew (ruinairas1992)]

Has there been any work on fixing this bug? I hope there is a workaround/fix for Ubuntu 12.10. Especially since Unity 2D has been removed from default installations.

[František Zatloukal (zatloukal-frantisek)]

No, i still need to use alternative DE for gaming.
I think it will be better to wait for https://launchpad.net/unity/6.0/6.4 .
A will be tommorow without internet access, so i can't test it. I'll write
you when i try out Unity 6.4.
And i can try gnome panel or shell - to desire where is bug (unity vs
compiz).

Bug is still present on Unity 6.4

[Daniel van Vugt (vanvugt)]

All,

This bug is marked Fix Released, so further comments generally won't get much attention.

If you still have a problem on:
  12.04: Please wait. This fix has not been released for 12.04 yet.
  12.10: Please ensure your system is fully updated and if the problem persists then log a new bug with:
      ubuntu-bug unity

[František Zatloukal (zatloukal-frantisek)]

I know, i´ve reported https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/1039045 .
I have latest packages :/

[Mateusz Stachowski (stachowski-mateusz)]

I'm using 12.04 and I don't have problems with running games in fullscreen (native and Wine). I'm using Unity from the SRU PPA and I have proposed updates enabled.

You should use CompizConfig Settings Manager and enable Legacy Fullscreen Support it's in Tools => Workarounds.

I remember that this option worked even before Precise was released.

[Clint Byrum (clint-fewbar)]

Hello Federico, or anyone else affected,

Accepted unity into precise-proposed. The package will build now and be available at http://launchpad.net/ubuntu/+source/unity/5.16.0-0ubuntu1 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please change the bug tag from verification-needed to verification-done. If it does not, change the tag to verification-failed. In either case, details of your testing will help us make a better decision.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance!

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[quequotion (quequotion)]

Unfortunately unity 5.16.0 does not fix this bug (completely).

There is still an edge case: bug 1025535

Steps to reproduce:

1. In CCSM, enable Desktop Cube
2. In Desktop Cube's settings, in the Transparent Cube tab, set "Opacity When Not Rotating" to any value less than 100.0000
3. Open an application capable of fullscreen (firefox, totem, etc)
4. Enter fullscreen (usually [F11] or [Alt]+[Enter])
5. Observe that unity obstructs the fullscreen window.

[Chris Halse Rogers (raof)]

The verification of this Stable Release Update has completed successfully and the package has now been released to -updates. Subsequently, the Ubuntu Stable Release Updates Team is being unsubscribed and will not receive messages about this bug report. In the event that you encounter a regression using the package from -updates please report a new bug using ubuntu-bug and tag the bug report regression-update so we can easily find any regresssions.

[Ricardo Salveti (rsalveti)]

Tested with Precise on ARM (Pandaboard) and the fix didn't bring any other side effect or regression, besides fixing the proposed bug. Was able to use Firefox at full screen without any issue with Unity.

[htrex (hantarex)]

Could you please implement a feature to optionally but completelly disable the top screen menubar on a secondary monitor?

With that bar Ubuntu with Unity becomed unusable for video art and gigs, where the secondary display output is used with projectors in live shows.

In such environments, on the unfortunate case of a problem with the application generating output on the secondary monitor, a small human error with the fader of a video mixer, or anything, showing a black background for a moment is more desiderable than showing an operating system interface for a moment.

[Daniel van Vugt (vanvugt)]

htrex,

There is already a bug requesting that enhancement, somewhere. However it sounds like you are describing bug 748539, so please look at that one instead.

[quequotion (quequotion)]

Has anyone tested the bug against compiz with the cube enabled and the cube transparent?

You will find that the bug has not been fixed.

[Daniel van Vugt (vanvugt)]

If anyone does have similar problems with cube transparency, please look at bug 1025535 instead.

[htrex (hantarex)]

tnx Daniel, I'll post my comment there.

[Pilot6 (hanipouspilot)]

When I start a fullscreen movie on a second monitor and open any window on the first monitor, unity is visible on the second.
Si fix does not work.

[Jg-staffel (jg-staffel)]

Yes, i can confirm that on Ubuntu 12.04 with two monitors.

[Daniel van Vugt (vanvugt)]

Pilot6, Jg-staffel,

You are describing bug 748539, not this one.

[quequotion (quequotion)]

>>John Lea

What does it mean when a fix is released for ayatana design?

[Daniel van Vugt (vanvugt)]

I just asked John. He says that Fix Released in ayatana-design means the design team has double-checked and verified the fix works and matches the intended design.

[Dong Liu (edongliu)]

I saw the same problem, and suspect it is related to gnome-tweak-tool, because the problem is gone after I remove that package.

[Alex Burdu (alex.burdu)]

i don't have gnome-tweak-tool and i'm encountering this problem in ubuntu 12.04 x64

[Mahendra Tallur (mahen)]

Hi ! It seems the bug is partly fixed.

In my case : Ubuntu 12.10, Nvidia proprietary drivers, up to date, when I open a fullscreen app on the second monitor, Unity dock & top bar do disappear, but they re-appear as soon as I click on something on the primary monitor.

I partly worked around it by setting the dock to only appear on the primary monitor but the top bar is still here.

[Mahendra Tallur (mahen)]

BTW, I noticed the top bar only appears when there's another app open on the main screen, otherwise it's properly hidden on the second one.

Actually, It seems there are all kinds of issues with dual-screen. For instance : the height of windows opened on the main screen corresponds to the max height of the secondary one ; an app like VLC will remember on what screen it was started last, instead of opening on the current screen etc...

[Loris Zinsou (nepenthes)]

Ubuntu 12.10, this bug is mostly fixed, but the top panel still appears on top of Wine virtual desktop if I start a Wine full-screen game.
The issue still appears in Trine 2 too.

[quequotion (quequotion)]

>> #108
Thank you for getting back to me on that Daniel.

How much testing constitutes this "fix"?

[bwat47 (bwat47)]

I see this bug a lot in 13.04 with latest updates, panel shadow shows in fullscreen video players like totem and smplayer

[variona (variona)]

I encounter this bug, on a LTSP client (shuttle XS35), other (older) clients and the server don't show this symptom.
that is also true for this bug: https://bugs.launchpad.net/compiz/+bug/886605

[timo (playsansara)]

This bug is definitely still present in 12.04 when playing wine games in full ścreen.

I've found that unchecking "allow window manager to decorate windows" and "allow window manager to control windows" in wine config will actually make the panel disappear, but also leaves you with no keyboard input...

Has anyone found a workaround without that major drawback?

[Roman (roman.kita)]

I can confirm.
Ubuntu 12.04, Radeon graphics card, single monitor.
In my case chromium was not affected and Eduards workaround described in bug 958353 works.
Having 2 accounts logged simultaneously I removed buggy behaviour for both of them.
However:
In the first account in the same time when this bug appeared my launcher icon size (horizontal size) has changed and became bigger. It become smaller again after workaround.
In the second account launcher icons stay bigger (it's ok for me). When applying workaround I had to type password blindly as Eduards described for the second account, but for the first account screen become black and a proper password window appeared.
I have no idea what triggered this bug.
After it appeared it was permanent in both accounts until now, I promise to play with it when it appears again.
By the way, is it possible to change launcher icons size (intentionally)?

[sgttynis (sgttynis-deactivatedaccount)]

I can confirm the comment from bwat47: in 13.04 the shadow of the global menu bar appears over full screen in video players (VLC in my case). For reproducing: play an video in VLC player (important: inital window size has to be normal) -> go full screen -> move mouse cursor to the bottom to open VLC overlay menu -> global menu bar shadow appear on top of screen. Curiously this will not happen when you have a maximized inital video player window state. I've seen the global menu bar shadow even while playing youtube videos in full screen, but its not reliable to reproduce. System: upgraded 12.10 (which didn't show this issue) to 13.04 using nVidia 310.44 properitary (Ubuntu tested) driver.

[quequotion (quequotion)]

After observing compiz behavior for a long time, I think Unity is being drawn in the root window (the first/top layer of the x11 display) first, before anything else. Because unity is drawn directly to the root window, no other windows, screen changes, lockscreens, screensavers, etc etc can ever be drawn over it. Shouldn't unity, like everything else, be drawn in a composite overlay window?

[Brandon Schaefer (brandontschaefer)]

The problem with this bug, and fixing this bug, is the fact that the unity launcher/hud/dash are all type _NET_WM_WINDOW_TYPE_DOCK windows. Which to obey the WM standards the launcher/dash/hud should have been _NET_WM_WINDOW_TYPE_NORMAL, and obeyed the stack to be pushed to the top of the stack when needed vs just kind of floating there atm.

The problem now, is changing nux XInput window to be of the TYPE NORMAL, while going through and making sure there are no regressions is a very difficult task. A lot of things lean on the fact that the launcher/hud/dash are all DOCK type windows ie. they don't obey the stack very well .... So a fix for this would be a huge regression potential, sadly :(

[Daniel van Vugt (vanvugt)]

Also remember that Unity does not use any "windows" in rendering at all. What is visible of Unity is pure GL (via Nux) and not dictated by normal window types/hints/states. The "windows" unity has and their types, exist only to receive input (mouse clicks).

Last year I did some work in unityshell.cpp to make it actually honour the window order and pretend that its input windows were real ones. This worked well for 12.10, but I think there have been some regressions in 13.04/13.10.

Still, whether you agree or not, please follow standard practice of logging new bugs and not continuing conversations on in those that are marked Fix Released.

[Brandon Schaefer (brandontschaefer)]

@ Daniel

I commented on the wrong bug it seem :), I was actually looking at the one where we want dash/launch/hud above the fullscreen window when pressing super...

Ignore my comment :)

[Arnaud Thevenet (aeromousse)]

My experience of it : in Darktable (photo editing software) when you hover over some area, a ballon tip is displayed. When the tooltip is displayed, the shadow of a transparent top panel appears.
I have no problem with fullscreen Firefox, but I think this is related and might help.

[Loris Zinsou (nepenthes)]

This bug is definitely not fixed for me ( Ubuntu 13.04, Unity 7.0.0daily13.06.19, Wine 1.6).

Many wine games running in a virtual desktop have the unity panel and unity launcher shown on top of them (actually, on top of wine virtual desktop, and the game window itself is off to the bottom by the exact unity panel height, and trimmed on the lower edge).

This does not happen in gnome-shell.

So, to reproduce this :
1) configure wine 1.6 to run a virtual desktop, with your exact screen resolution
2) start a Windows version of any recent Unreal Engine game in wine (XCOM ; Enemy Unknown, Dishonored...)

This may not happen without wine virtual desktop but these games do not run without it on nvidia optimus laptops.

[Loris Zinsou (nepenthes)]

Here is a screenshot of the issue.

[Loris Zinsou (nepenthes)]

Setting wine not to control windows does not help in this case.

[turbolad (turbolad995)]

Unity and Ubuntu 13.04 (64-bit)...
Unity prevents DOSBox from toggling between fullscreen and windowed mode, more than once, with the Alt+Enter keys (you hold down Alt and press Enter). I also use LXDE in Ubuntu; DOSBox accepts the Alt+Enter keys every time under LXDE. This confirms that Unity is stopping DOSBox from toggling between fullscreen and windowed mode.

Is this bug the culprit?

[quequotion (quequotion)]

>>turbolad

No, this bug is just a graphical glitch. The symptoms of this bug are being able to see, but not interact with, Unity's panel or launcher on top of fullscreened (Alt+Enter/F11) windows. It doesn't affect keyboard interaction.

In some cases it may affect mouse interaction, if the panel or launcher are responsive at all (they usually are not, because input is layered correctly in X11).

[Jussi Lind (jussi-lind)]

This still happens with full screen Qt/OpenGL apps in 13.10.

[quequotion (quequotion)]

>>Last year I did some work in unityshell.cpp to make it actually honour the window order and pretend that its input windows were real ones.

Do you recall a specific release version in which those changes were working?

I'd like to try it out, since I have never seen unity /not/ having this problem.

[Mathew Hodson (mhodson)]

The proposed package unity - 5.16.0-0ubuntu1 was released, so removing the verification-needed tag.

[snapy (sdfjsfjaei-hans)]

I still have this bug in Ubuntu 14.04 (up to date) with Trine 2. When I accidentally press ALT, the unity launcher is always visible.

[Marc Rene Schädler (suaefar)]

Happens to me in Ubuntu 14.04 LTS with Diablo2 on wine.

[quequotion (quequotion)]

Have I mentioned before that I think this is a layering problem?

I was reading the old xscreensaver (one of many things unity appears on top of) faq and came a across this:
__________________________________________________________________
Every few minutes, xscreensaver will raise itself above any other windows that have popped up, but it can't prevent other programs from popping up their windows in the first place. So they will appear for a little while, and then be hidden.

If this is happening and it bothers you, switching to a different window manager may fix it.

You might consider this a bug in your window manager (though some consider it a feature.) If you think it's a bug, then the magic incantation to repeat to the author of your window manager is as follows: "you should be mapping windows with XRestackWindows instead of XRaiseWindow, to ensure that managed windows always appear below override-redirect windows."

It is also possible that the application that is popping up the window is doing so using an override-redirect window of its own. (This is currently the case with GTK_WINDOW_POPUP style dialogs.) In that case, it is impossible for either xscreensaver or the window manager to prevent those windows from popping up, since override-redirect windows, by definition, bypass the window manager.
__________________________________________________________________

Is Unity drawn using override-redirect? Is it mapped with XRaiseWindow?

[tonyhartfield (anthony-hartfield)]

I have this bug in ubuntu 14.04 however only when using a certain display configuration.

I have an nvidia graphics card and I typically use 3 displays, 2 monitors and a TV connected via HDMI cloning the output of one of the dual monitors.

In this configuration its not possible to have any full screen application open without unity appearing on top of the application. If I switch the TV to being a separate display rather than using the clone option the problem goes away.

[Federico Cupellini (fedecupe)]

This resets your Unity settings but is a valid workaraound and solves the problem

sudo apt-get install dconf-tools
dconf reset -f /org/compiz/
setsid unity

[liamdawe (liamdawe)]

Just to let you know, this issue still happens in Ubuntu 16.04.

Specifically when running a full screen game at a lower resolution than the desktop.

[BronsonMathews (bronsonmathews)]

Yes this bug is still around, and rather annoying!!
Is this due to be fixed on 16.04?

Maybe the choice of not having the top menu bar visible on the second screen would be an option also

[quequotion (quequotion)]

Ages ago, someone decided that Unity would need to draw itself while using plugins like "desktop wall"...

I suspect the solution they came up with was to draw Unity directly into X11's root window where nothing can ever be drawn on top of it.

[Daniel van Vugt (vanvugt)]

Unity isn't drawn into X11 at all. Unity is a Compiz plugin and Compiz paints everything including the root window, in whatever order the Compiz plugins desire.

Compiz is able to paint anything, including outside of X11 windows. And that's what the Unity shell is -- outside the realm of X11 windows. It's just pure OpenGL.

[quequotion (quequotion)]

I see..

So any idea why nothing has ever been able to draw on top of unity?

[Daniel van Vugt (vanvugt)]

It's impossible for an X app to draw on top of the Unity shell because the Unity shell is part of Compiz and designed to always draw after app windows (hence appears on top).

If you want the appearance of Unity not being on top then you need to modify the Unity code so that it doesn't draw itself on top, or not draw itself at all under certain conditions.

[Serge Hallyn (serge-hallyn)]

Interesting wording, "you need to" - does that mean this bug should be marked wontfix or opinion?

[Daniel van Vugt (vanvugt)]

My wording is because I don't work on Compiz/Unity any more. "You need to" refers to someone else, anyone else :)

Also, I just noticed this bug was marked Fix Released four years ago. I understand people continue to have trouble and it's not really fixed for some cases, so the correct thing to do is to open a new bug. Because "Fix Released" bugs don't show up in searches and generally should not be reopened if they've been closed this long, even if closed in error. Adding comments to this bug is not the productive way forward.

[Serge Hallyn (serge-hallyn)]

Gotcha, thanks. (I'm not using unity so haven't seen this re-appear.
Though I also don't recall it ever having been fixed)

\o

[quequotion (quequotion)]

Comment #96 lists this bug as fixed in release 5.16.0-0ubuntu1, but I *know* that is not true. As Daniel has pointed out, the underlying issue is that Unity draws itself above all other windows in X11. Unless this behavior is changed--and it was not in 5.16.0-0ubuntu1--Unity will always be visible over full-screen apps--as it always has been.

Not that it really matters; Unity is one of the things that drove me away from Ubuntu and I no longer use either. It seems Unity drove so many users away Canonical finally had to give it up. I am not surprised.

I do hope it doesn't mean the end for (Ayatana) Compiz. Ubuntu's fork of compiz is still much lighter and more advanced than compiz-core, despite the lack of flashy plugins.
