X11 window (usually AnyDesk) at top-right of the screen is invisible and steals mouse clicks

[Mauro Gaspari]

[ Impact ]

In X11, some tray icons are covering areas they don't own, preventing events to reach to the windows under the cursor

[ Test case ]

- Launch Ubuntu in Xorg session
- Download anydesk client for Ubuntu from
  https://anydesk.com/it/downloads/linux
  WARNING: Installing software from any untrusted deb (such as the
  closed sources ones) is at your own risk!
- Optionally install hexchat from ubuntu repository
  It triggers the same bug but is harder to reproduce
- Launch the test applications
- Clicking in the icons should make the application actions to be
  triggered
- Clicking anywhere else on the screen should behave as expected and
  events should not be stolen by the apps in the tray.

[ Regression potential ]

- Tray icons are not shown
- Tray icons size is not matching the expected ones

There's a behavior change that is actually a bug fix (it wasn't ever
supported by the shell until couple of releases ago, but it started working
due to an incomplete code refactor):
 - Tooltips aren't shown anymore when hovering a tray icon, again, this is
   by design.

[Daniel van Vugt (vanvugt)]

Looks like we've leaked a picking rectangle/actor from either an indicator or the aggregate menu.

Please try:

  gnome-extensions disable <email address hidden>
  gnome-extensions disable gTile@vibou
  gnome-extensions disable <email address hidden>

and possibly others from 'gnome-extensions list' :)

You might also be able to find out what the rectangle *is* by:

 1. Alt+F2
 2. Type: lg
 3. Click the target icon
 4. Move the mouse over the problematic area

[Mauro Gaspari (ilvipero)]

Thank you for your help. I have been running some tests:

- Disabled all extensions and re-logged the sessionSame result. However, when hovering over the previously mentioned rectangle, I noticed that a popup was appearing, repoting "Anydesk", an application that was set to autostart and had an icon on the taskbar.
- Presto I went to prevent this application from auto starting on login, and I cannot reproduce the issue any more.
- I re-enabled all gnome extensions, left Anydesk with autostart disabled, and re-logged. I cannot reproduce the issue.
- I have other applications that are set to auto start and have a taskbar icon, such as ProtonMail Bridge, Nextcloud client, and Polychromatic. However I cannot reproduce the issue with those applications.

Note. I have been using Anydesk for a long time and on Gnome and this is the first time I saw this problem. Do you believe it is worth exploring more about this issue or consider this resolved? I am happy to help if needed.

[Daniel van Vugt (vanvugt)]

I think it's worth exploring first by reporting a bug upstream to Anydesk. However you do that.

[Daniel van Vugt (vanvugt)]

If you run 'xwininfo -all' and then click on the rectangle, what do you get?

[Mauro Gaspari (ilvipero)]

I am trying to report the bug upstream and jumping through the required steps to create a customer account, waiting for it to be activated. I will report back on that if I manage to actually file a bug there.

Regarding your question to run 'xwininfo -all', please find output below here.

[Daniel van Vugt (vanvugt)]

Thanks. So "AnyDesk" is a real 200x200 window of class InputOutput. Since it has "Override Redirect State: yes" it will always be on top. Just the fact that it's completely transparent means you can't see it even though it still consumes the mouse clicks.

So the bug in AnyDesk is either than it's failing to render anything, or failing to hide itself when unused.

[Daniel van Vugt (vanvugt)]

Although if you try logging into a Xorg session and a window is actually visible there, then this would be a rendering bug in mutter/gnome-shell.

[Mauro Gaspari (ilvipero)]

I logged into a Xorg session and I could not see the window.
However, I noticed I can actually see the window for a few moments, both on Wayland and Xorg, when I switch between virtual desktops.

There is a small difference is when I switch between virtual desktops:
- Wayland: the window appears for a moment, and it looks black
- Xorg: the window appears for a moment, and it looks like Anydesk icon

I am attaching a short video I took from Xorg session.

[Daniel van Vugt (vanvugt)]

Thanks, it looks more like a bug in AnyDesk now.

[Mauro Gaspari (ilvipero)]

I managed to file a bug with AnyDesk, and I linked this Launchpad bug report in it.
However, I was not given a bug tracker link by AnyDesk, so I am unable to provide it here.

[Rasmus Pedersen (sundowndk)]

I'am also affected by this bug, and even after closing/stopping Anydesk the transparent window is still there. Sometimes it manifests itself as black square and sometimes as the Anydesk logo.

However, I found that disabling support for "Legacy Tray Icons" in the Ubuntu Appindicators extensions it goes away. So does the Anydesk tray icon, but I can manage without the icon for now.

[Jürgen Hörmann (hoermannn.j)]

This is not a bug in Anydesk.

I can reproduce this with at at least one more application (Zoiper 5 Desktop).
If I hover over the "ghost" area I get mouse pointer hints for both, Anydesk and Zoiper on different parts of the area.

If I disable the "legacy tray icons" option in the extension and log out of Gnome session and log in again, the ghost-area is gone.

To me, this looks like a problem in the handling of the legacy tray icons.

[Daniel van Vugt (vanvugt)]

Yes that explains why it suddenly became a problem in 23.04.

[Luis Alvarado (luisalvarado)]

Hi Daniel, just in case this is not an Anydesk bug. I installed anydesk today but I have had the issue since the first day I installed Ubuntu.23.04. I am saying this because my bug report was marked as duplicate of this one but it is not an anydesk issue. I did not even have anydesk installed since today.

[Luis Alvarado (luisalvarado)]

If I disable the "legacy tray icons" option...

How can I disable the legacy tray icons to try to replicate this? Just to test it thoroughly.

[Enrique Rojano (kikezzdrums)]

Open gnome-shell-extension-prefs, scroll down to 'Ubuntu Appindicators' and disable it.

I already did, and icon tray stopped stealing click actions.

'Enable Legacy tray icons' is an option of 'Ubuntu Appindicators' extension. You can see it if you click on Settings at 'Ubuntu AppIndicators' extension, but disabling only that setting did not work for me, I had to disable the entire extension.

[Sebastien Bacher (seb128)]

@Daniel, you said that's a newer issue, did we change the default of that option?

[Enrique Rojano (kikezzdrums)]

When disabled 'Ubuntu AppIndicators', clicks at minimize worked ok; but later, those clicks stopped working again even with all extensions disabled :/
Update: Discovered that I was clicking at an specific pixel that is not stollen by the icon tray.

I noticed that even the 'hover' mouse action over minimize-restore-close buttons, does not trigger.

[Enrique Rojano (kikezzdrums)]

Attached video reproducing how mouse pointer does not affect windows at certain point at top-right corner.

[Jürgen Hörmann (hoermannn.j)]

@kikezzdrums.
If you disable/uninstall gnome-shell-extension-appindicator or disable the legacy tray icons option, you have to log out of your active gnome session and re-login again. If you do not log out, the bug will still occur.

[Jürgen Hörmann (hoermannn.j)]

@vanvugt
This bug is also present in Wayland session, not only on X11. Maybe it makes sense to cover this in the bug report title.

[Enrique Rojano (kikezzdrums)]

Yeah, thankyou @hoermannn.j it worked that way.

[Luis Alvarado (luisalvarado)]

It might be me going crazy (just in case). But I am getting the feeling the invisible box sometimes grows downwards, taking more space so even if you drag windows down, you can not click them unless you drag them to the left side of the screen. It also grows in a specific rectangular way. What I mean with this is that, when dragging windows for example you can not drag them in a certain part of the window (because of the ghost window) but any other part to the left or right will work. Here is an image to give you an idea:

https://imgur.com/a/e5UjluM

Inside the red, I can not drag either the telegram app or sublime in the background, but if I move the mouse over to the right or left I can drag/click again.

[Yohandra (yohandra)]

Hello everyone, so I updated 2 days ago from 20.04 to 22.04, then to 22.10, and lastly to 23.04. After which I am also experiencing this problem. I do not have any of the apps mentioned above like anydesk. But I do have that weird issue that I can not click on buttons when a window has the button in a ghost zone as mentioned.

[Daniel van Vugt (vanvugt)]

If you run 'xwininfo -all' and then click on the rectangle, what do you get?

It's the "has no name" window :(

Please try running 'xprop' and then clicking on the window and paste the output here.

Hi Daniel, I got this:

I have this problem as well.
Disabling the Gnome extension Ubuntu AppIndicators and rebooting works as a workaround.

[Luis Alvarado (luisalvarado)]

If it serves any purpose. When the error happens and you go play CSGO there is a gray area at the top as seen here https://imgur.com/a/uAQe3N9

[Luis Alvarado (luisalvarado)]

I followed the advice of Disabling the Gnome extension Ubuntu AppIndicators and rebooting which worked, but today I am seeing the following, if I click around the area in the circle it opens anydesk. This time, it ONLY happens to anydesk, not telegram or any other app in there.

https://imgur.com/a/xGfBu4H

[Daniel van Vugt (vanvugt)]

Sounds like we have two bugs:

1. gnome-shell-extension-appindicator

2. AnyDesk

[Luis Alvarado (luisalvarado)]

Hi Daniel, well you are 100% right. We tested with a German friend the following:

1. Ubuntu 23.04 with gnome-shell-extension-appindicator ONLY

2. Ubuntu 23.04 with AnyDesk running only

3. Ubuntu 23.04 without both.

Only by removing BOTH did it work correctly.

There is however a weird behavior also where, when you click the system bars at the top of an app, they do not get selected. you need to drag the windows for them to get focused.

[Luis Alvarado (luisalvarado)]

Here is more information. This is without the gnome extension and anydesk:

[Hiroaki Hashi (hashiz)]

I have same issue with Zoiper 5.

[Luis Alvarado (luisalvarado)]

Yes a lot of people are having it, but it is being worked on. I ended up removing anydesk completely because of this but the ghost area is still there. Nd it is horrible for a workplace. We just gotta wait. Soon the fix will be there.

[Climax (pieterwjordaanpc)]

Removing just anydesk worked for me. I'll try the same with appindicators disabled and anydesk still installed. NOTE only works after rebooting. Signing out/in does not work it seems.

[Luis Alvarado (luisalvarado)]

Same for me. It worked after deleting Anydesk and disabling the appindicator, but after around 30 minutes to 4 hours, the issue appeared again.

I then removed telegram, removed flameshot, removed cpufreq and even vital and clipboard. Again, after 30 minutes to several hours, the issue appeared again randomly. The only things left on the task area was the default icons for network, sound, microphone and power.

[Luis Alvarado (luisalvarado)]

I gotta update something here that I have noticed. Whenever the problem happens, any window on the system, when trying to click on it to get it focused on the system top bar, it will not handle the click, you would have to drag the window a bit to get it to focus. So basically, when the problem happens:

1. Try to click the top system bar of any window for it to get focus.
2. It won't work, so you need to drag the window for it to get focus

[Climax (pieterwjordaanpc)]

For me, disabling the legacy app icons extension and rebooting fixed it. I was able to install Anydesk again without issue. Of course, my Anydesk tray icon is not showing with the extension disabled...

[Security XIII (securityxiii)]

Important note: this is not only Ubuntu bug. I've got legacy tray icons enabled and AnyDesk as well on Garuda (Arch-based) Linux. Same thing here - invisible box with everything you're describing here. So, basically, I bet this bug affects almost all families of distributions.

[Joe Bennett (kralos)]

I'm also having this issue on 2 separate computers. Both have Zoiper installed as we use it at work. I do not have anydesk installed

[Abdullah Faheem (controloye)]

Hello everyone,

temporary fix is just to disable AnyDesk in startup service.

I have disabled and now everything works perfect. Even if I open AnyDesk manually it does not override.

open terminal and run

sudo systemctl disable anydesk

:-)

keep posting if somebody have other fix.

[Abdullah Faheem (controloye)]

note:

sudo systemctl disable anydesk

after running this command you have to reboot your PC.

[Santiago Alves (santiagooooo)]

Don´t work for me:

"sudo systemctl disable anydesk

after running this command you have to reboot your PC."

I enable the gnome in terminal again and execute this command mentioned, but the bug remained after the reboot

[Daniel van Vugt (vanvugt)]

Try:

  gnome-extensions disable <email address hidden>

[Luis Alvarado (luisalvarado)]

Good morning Daniel, just updating you that I have tested for 7 days already. Your suggestion works beautifully.

[Luis Alvarado (luisalvarado)]

I am enabling <email address hidden> just for a couple of days to test out. Before, everything was working but of course I was unable to see the apps I had there like steam, telegram or flameshot.

[gaurab (gaurablahkar)]

For me it works by disabling anydesk. After disabling anydesk, reboot is required to take effect.

[Davi Medrade (davimedrade)]

I have this bug with AnyDesk. Like, disabling AnyDesk autostart prevented the bug from happening as soon as I logged in, but it would still happen as soon as I opened AnyDesk (to connect to another computer or to allow someone else to connect to mine). Whenever I clicked the invisible square, another AnyDesk window would open. Then even if I closed AnyDesk the “invisible square” would still be there, but it would be dead (clicking on it wouldn't do anything, but would block the click from reaching the window beneath it).

By the way, yes, rebooting or logging out and logging back in fixes the issue when it happens, but it's not necessary to go that far. Restarting the shell is enough. Here's how:
1. Quit Anydesk (or whichever app triggers this bug in your computer). Make sure that it's not running in the background (for AnyDesk, right-click the tray icon and close the app from there, so that the app closes and the tray icon disappears).
2. Restart the Gnome Shell: hit Alt+F2 to open the “Run a Command” window, type the command “r” (yes, just a lowercase letter “r”, without quotes or other parameters) and hit Enter.

That makes the bug go away (until Anydesk or another app that triggers it is started again) without forcing you to close all your programs. But, as stated, the problem with this is that once you start the app again the bug will happen again (so once you're done with the app you have to do steps 1 and 2 above again).

The workaround I ended up adopting was disabling legacy tray icon support.

The extension I use is “AppIndicator and KStatusNotifierItem Support”, and I didn't even have to disable it completely; I just had to go into the options and disable the option “Enable Legacy Tray icons support”. Just disabling the option does not get rid of the invisible square in the current session, so if it's already there you'd have to perform steps 1 and 2 above one last time. Now I can use AnyDesk without getting that invisible square. One small downside is that the AnyDesk tray icon doesn't appear anymore, but I can live with that.

[Daniel van Vugt (vanvugt)]

Marco has assigned this to himself internally so assigning here too.

[Jack Kowalski (jackkowalski1865)]

Temporary solution:
1. jack@jack:~$ xwininfo
2. Click on the invisible square in right top corner
3. Get the square ID (Window id):
"
> xwininfo: Please select the window about which you
> would like information by clicking the
> mouse in that window.
>
> xwininfo: Window id: 0xc02f07 (has no name)
"
4. jack@jack:~$ xdotool windowclose 0xc02f07

I need to do this every time i use AnyDesk

[Mauro Gaspari (ilvipero)]

I would like to add a quick update.

- HexChat also triggers the same issue as Anydesk, both wayland and x11.
- I upgraded to Mantic Minotaur and the issue persists
- I disabled legacy tray icons support from the extension Ubuntu Appindicators, and after a reboot the issue cannot be reproduced. Obviously HexChat icon does not show up on the tray, but it does on the dock, so it is a decent workaround for me until a fix is in place.

[andrei (andrewternity)]

I inform you there is the same thread here https://github.com/ubuntu/gnome-shell-extension-appindicator/issues/439
I also attach picture how any user can fix problem.

[Daniel van Vugt (vanvugt)]

The video in bug 2039543 looks like it's related to this.

[JSigma (jsigma)]

Thank you for the assistance in this topic, particularly with xwininfo. I've resolved the Anydesk issue with a small bash script, which I execute via an alias to close Anydesk.

@JSigma thanks a lot for your script! Works on Fedora. I added "sleep 5" before the window_id line, added a menu entry so I can add the script to startup applications in Tweaks. Anydesk gets killed on startup, excellent!

[Miguel Elias Machado (miguelemachado)]

Even though I'm not using anydesk, I experience the same problem. And I think its caused by "dropbox"

This workaround seems to work

[Daniel van Vugt (vanvugt)]

Marco says he has tracked the issue back to gnome-shell itself.

[Juliano Lopes (jlm1real)]

Hey Daniel, good night, thks for the help and the forum link. I solved the
problem with the following steps
1- create script file in this location
      nano /usr/local/bin/fechar_anydesk.sh ("fechar" means close)
2- paste the following script
       #!/bin/bash
window_id=$(xwininfo -root -tree | grep -E "200x200" | grep -E "\(has no
name\)" | awk '{print $1}')
if [ ! -z "$window_id" ]; then
    flatpak kill com.anydesk.Anydesk > /dev/null 2>&1 &
    xdotool windowclose $window_id
fi
3- ctrl + o, enter, ctrl + x
4 - make the file executable
      chmod +x fechar_anydesk.sh
5- execute the script on terminal
    fechar_anydesk.sh

i run the script every time when I turn my pc, and have been worked for me
=)

[Daniel van Vugt (vanvugt)]

The fix looks complex so I'm not suggesting it should get rushed into 24.04 in a hurry. Just nice to have. It would also make sense to wait until the fix gets some upstream review.

[Ann (onglaodanhca123)]

now the error still persists when using anydesk on ubuntu 24.04. Can someone tell me when the bug will be fixed?

[Daniel van Vugt (vanvugt)]

Marco, can you imagine a simpler patch we can use in backporting to Noble?

[Łukasz Zemczak (sil2100)]

Hello Mauro, or anyone else affected,

Accepted gnome-shell into noble-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/gnome-shell/46.0-0ubuntu6~24.04.1 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 on 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 add a comment to this bug, mentioning the version of the package you tested, what testing has been performed on the package and change the tag from verification-needed-noble to verification-done-noble. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-noble. In either case, without details of your testing we will not be able to proceed.

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

N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days.

[Alan Knowles (roojs)]

Confirmed
gnome-shell_46.0-0ubuntu6~24.04.1_amd64.deb
gnome-shell-common_46.0-0ubuntu6~24.04.1_all.deb

Fixes this issue for me - not seen any other problems yet.

Thanks Lukasz / Marco

[Mauro Gaspari (ilvipero)]

I also confirm I am unable to reproduce the issue with the latest updates from proposed repository.

Release: Noble Numbat
Package version:
- gnome-shell_46.0-0ubuntu6~24.04.1_amd64.deb
- gnome-shell-common_46.0-0ubuntu6~24.04.1_all.deb

Steps to recreate:
On Noble Numbat, I re-enabled legacy tray icons and I was able to recreate the issue.
I then enbled the proposed repository and installed gnome-shell from it.
Rebooted and after logging in I was unable to recreate the issue. I no longer see black rectangles when switching virtual desktops, and nothing is stealing mouse clicks any longer.

I would like to thank everyone involved troubleshooting, fixing, and backporting patches to Noble Numbat.

The verification of the Stable Release Update for gnome-shell has completed successfully and the package is now being 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 regressions.

[Robie Basak (racb)]

An upload of gnome-shell to noble-proposed has been rejected from the upload queue for the following reason: "GNOME MRE not valid for gnome-shell as discussed in bug".

[eXcuvator (excuvator)]

I just installed Ubuntu LTS 24.04 and Anydesk.

I am observing the bug (when I click into the upper right corner, which is supposedly empty space, Anydesk opens).

I am on X11 and
$ gnome-shell --version
GNOME Shell 46.0

I understood the comments above as "This is fixed if you have gnome-shell 46.00" -- am I wrong?

[Daniel van Vugt (vanvugt)]

You need the package version to be "46.0-0ubuntu6~24.04.1"
