Maximized windows go under panel if panel attached to screen edge between two monitors

[kolen]

Maximized windows go under KDE Plasma panel (even if panel is configured as "Always visible") if such panel is attached to edge of screen that acts as border between multiple monitors

(i.e. right side of first screen or left side of second screen if monitors are arranged horisontally).

I have a panel on the right side of the left screen.
Even if I set the panel "Always visible" it behaves as "Window do under".
See the image linked.
I would like to have this like 2 years ago, it is annoying and works in windows :)
(Gnome has the same problem eather)

Reproducible: Always

Steps to Reproduce:
1. create a vertical panel on dual monitor setup, in the middle
2. maximize a window
3. the window goes under the panel :( !
Actual Results:
the window goes under the panel :( !

Expected Results:
the window should be smaller, to not go under the panel.
The behavior of the bottom panel is correct, and this should be the same for the vertical panel.

I made some tests and realize that it aways happend on the panel that are on the side of the screen that joint with the other screen.

[Csabi (csabi-m)]

yes, exactly, your description is better.

[Zach Leigh (zachleigh-8)]

Same problem here but with a bottom horizontal panel. Maximized windows go under panel regardless of settings.

Dual screen set up, Kubuntu 13.04, KDE 4.11

[Zach Leigh (zachleigh-8)]

Solved my issue. The program kscreen was held back during the update to KDE 4.11. Once I installed the current version (kscreen 1.0) and rebooted the problem was corrected.

I use kscreen 1.0.1, but still have this problem (under Ubuntu 13.10).

[V-baskoff (v-baskoff)]

Hi,
It seems the same issue... the window goes under the vertical panel on maximizing (see v-baskoff_desktop screenshot in the attachments)
I am using two monitor setup. Right one(27" 1920x1080) is main, the left one(15" 1024x768) is additional, mostly for "yakuake" console

Are there any chances to workaround/fix this?

[Albi-m (albi-m)]

I am having this issue too.
Kubuntu 13.10, KDE 4.12

[Razor-zhenya (razor-zhenya)]

The same on the OpenSUSE... and it's really annoying!!

[Freebullets-03 (freebullets-03)]

Also happens with 2 screens above and below.

[Konstantin (gor-konstantin)]

This mainly happens when you have two screens, and one of them has a bigger height (i.e. vertical). When you align the one with default panel to the top of second display (with bigger height) bug disappears, but of course this configuration is hard to use.

[Csabi (csabi-m)]

It happens also if the displays have the same size.

Since clearly nobody cares about this disturbing bug, I would be willing to fix it myself, just please give me some points what source should I download and some directions where to look.

[Philip Muškovac (yofel)]

Isn't this a dupe of bug #94470 (and bug #299247 ) ?

[Philip Muškovac (yofel)]

Hi there!

Thanks for reporting this bug! Your bug seems to be a problem with the KDE program itself, and not with our KDE packages. But don't worry! This issue is being tracked by the KDE developers at: https://bugs.kde.org/show_bug.cgi?id=94470. Once fixed in KDE, it will be included in Kubuntu once the KDE version the fix is in in reaches Kubuntu.

Thanks!

[theshowmecanuck (iambill)]

It is impossible to say for most people if this is a duplicate https://bugs.kde.org/show_bug.cgi?id=299247 since the description on bug #299247 is complete opaque and not understandable to anyone who isn't in some inner circle.

[theshowmecanuck (iambill)]

Multiple monitors is VERY common and this bug prevents people from maximizing application windows which is a pain in the ass. This is a usability issue. I'm not sure why this hasn't even been assigned.

[Mo-mashi69 (mo-mashi69)]

20freaking15 (that's two years and 3 months and after the start of this thread) and this bug is still happening. My windows are still going under the panel on KDE 5.4. Man, I left KDE in favor of gnomeshell 3 years ago because of stuff like this. It's 2015, I really wanted to give KDE a chance but your stuff is so unstable. I like KDE more then Gnome but in the month I've used KDE, I've had more bugs then I had in the last 3 years of using Gnome Shell and I started using Gnome Shell because KDE was unstable 3 years ago at 4. Guys, stop adding new features in KDE and iron out those bugs instead. The value you add by putting these new features get negated by all the bugs that aren't being addressed. This bug isn't even the worst example of old bugs completely unresolved, I got bugs on my 2015 distro that I've found bug reports from 2011. They got ignored, flagged as unconfirmed.

[Mo-mashi69 (mo-mashi69)]

sorry, I must have hit that comment button twice. didn't want to spam, just really frustrated.

[Milian Wolff (milianw)]

Never seen it with plasma 4, but now I keep having it on my laptop with plasma 5.

Anything I could try out to fix it?

[Mark-olenik (mark-olenik)]

Same problem here on dual monitors.

[Csabi (csabi-m)]

yes it's present in Kde 5 as well.

Finally I found a workaround. Install the tint2 panel, and place one 1 pixel high and the same width as the plasma panel. This is able to keep the windows from covering it, and therefore they will not cover the kde panel either.

[Xebec (xebec-yandex)]

Ubuntu 14.04. Kubuntu desktop package installed afterwards. Two screens. The smaller one has the panel. Windows go under it regardless of the settings.

[Oleh Prypin (oprypin)]

Thank you for this "tint2" workaround. Now I can do my work.
As a bonus, I used the clock provided by it, because in Plasma 5 the time format can't be customized anymore.

[Shadowisfading (shadowisfading)]

I have the same exact problem with kde5 with manjaro, dual monitor. Never had something similar while using kde4...

Considering is open since more than 2years maybe it's time someone set a higher priority on this.

[Eric J Schwarzenbach (ericjs)]

> I have the same exact problem with kde5 with manjaro, dual monitor. Never had something

Ditto here, with Chakra. Wasn't a problem with Plasma 4.

[Eric J Schwarzenbach (ericjs)]

Could someone please change the Product to plasmashell on this issue since people are confirming this as existing (or even worse) in Plasma 5? Or do we need to open a new issue?

[Vedran Furač (vedran-furac)]

Same here with dual monitor setup. Tried changing settings and moving panel up and down. Didn't help.

[Peter Hoeg (peterhoeg)]

For me, this bug only triggers when the panel is placed between the monitors. If I move it from the right side of the left screen to the left side of left screen everything is OK. Same thing applies to the right monitor in the inverse.

This is supposedly a limitation in X that requires panels to be flush against an absolute edge.

[Shadowisfading (shadowisfading)]

I think panels are having a lot of problems with absolute/relative edges with external monitors

Look what happens when I click on the menu widget (this is my external monitor)... the menu should pop up right above the panel as usual (and this correctly happens when I just use the main screen of my laptop) but, instead, it pops a lot higher than expected without reasons

[krgailey (krgailey)]

Same for me as Shadowisfading's comment:
"I have the same exact problem with kde5 with manjaro, dual monitor. Never had something similar while using kde4..."

I've lived with it since upgrading to 5. Just implemented the the 1 pixel length, same height tint2 workaround from Asadi above. It works well. Thanks!

[Elvis Stansvik (elvstone)]

Is anyone looking into this? It's an almost 3 year old "major" bug.

It's highly irritating because many applications have a statusbar or other elements at the bottom which gets hidden if maximized. So I have to manually adjust the height of the window to see it. But if I do that, the window gets "de-maximized", making it impossible to just slam my mouse cursor to the top-right and click to close it (breaking Fittz law).

[Elvis Stansvik (elvstone)]

Btw, the monitor/screen layout I'm using is:

xrandr --output DP2-2 --mode 2560x1440 --primary --output eDP1 --mode 1920x1080 --left-of DP2-2

That is, the laptop panel (eDP1) to the left of my external monitor (DP2-2), which is my primary output.

[D-aaron-9 (d-aaron-9)]

Kubuntu 16.04, two monitors, one on the right and one on the left. I like a vertical taskbar on the left of the left screen. When I maximize stuff, it goes under the taskbar. AARGHH.

[D-aaron-9 (d-aaron-9)]

Ok, here's what just happened, which appears to be a bug with the bug tracking system here. I hit post on the first one, realized my left / right mistake, hit the "stop" button on my browser, edited, re-posted. I was sent to the "mid-air collision detected" screen where there was an option called something like "post only my new post" and that sounded right. Seems it didn't work.

[Barafu-albino-cheetah (barafu-albino-cheetah)]

Arch linux, plasma 5.6.4. The bug is still here.
With dual monitors, when a panel is attached to the edge between the monitors, the windows go under that panel, no matter what the panel settings are.

[Harel Amnon (harelamnon)]

Gentoo, 4.14.16. Run into at least one of these bugs. It was triggered when I moved the smaller display to the left, but no matter what positioning I now try, the bug remains. Trying to get used to working without maximizing any windows. Maximizing was nice, been using it for 30 years or so. Oh well.

[Dennis Schwertel (tmassassin)]

same here. dual monitor setup with panel on the left edge.
the bug started to occur when upgrading from ubuntu 15.10 to 16.04

[Malte-e1 (malte-e1)]

Same here, currently I keep my laptop in front of my external monitor and have set it up to be above the laptop monitor. Windows go under the bottom panel. I have tried just disabling the laptop monitor, although I sometimes need it or arranging screens horizontally although physically they are arranged vertically. Very annoying. If wayland worked with dual monitor, I'd just be using that but it still seems quite far from being usable.

[Patrick Grimbergen (patrilk)]

I have the same problem since I upgraded to Kubuntu 16.04 with:
KDE Frameworks 5.18.0
Qt 5.5.1 (gebouwd tegen 5.5.1)

However, I only have one screen on my laptop though. The issue is on the second panel. My primary panel is ok.

[E-anima (e-anima)]

Same here with 4 screens. I think it is because one screen has a different resolution.

[Korbinianmoser98-f (korbinianmoser98-f)]

I had the same problem with my laptop (1600*900) on kubuntu 16.04 and an external screen (1920*1080). I was able to solve the problem by setting the external screen as primary display in the displaysettings

[Voicu Hodrea (hvm2hvm)]

Hello,

I'm experiencing the same issue but I do not have a dual monitor setup (although I did have one at a point so it might still be related?).

When I log in (sometimes?) the panel which is set as vertical on the left side overlaps maximized windows. I.e. I log in and if I start Firefox which opens up maximized, the left side of Firefox will be under the panel.

If I unlock the panel and go to its settings and resize it just a bit it, the windows maximize to the panel's edge as they should.

Maybe this helps with debugging.

Thank you

[Danny Howard (dannyman)]

I have experienced this bug on multiple systems, under 14.04, 15.10 and 16.04. Workaround in comment #55 here to set display to primary helps.

I also frequently lose the panel on boot or resume. Sometimes an old panel will reappear later.

FWIW, I like to keep my panel at the top of the screen.

[Mark A Gerads (nazgand)]

This bug is also present when there is only 1 monitor. I have a 4K monitor, and the panel works correctly when it is at the bottom of the screen, but when I move it to the top of the screen where I want it to be, suddenly the maximized windows or newly opened windows go below the panel.

[whochismo (whochismo)]

I think I'm having the same problem in Kubuntu 22.04. When I use two screens it's fine, but If it boot the laptop with just its screen, maximized windows go under the panel. The only workaround I found is to change the screen resolution and then restore it. But it needs to be done manually on each boot.
