Debian 12: zoom crashes just after login


I have a 64 bit PC. I have recently installed Debian 12 (bookworm).  I went to the zoom web site and installed zoom.  The deb file is "zoom_amd64.deb".  Inside this file, at the end, it says:

Version: 4
Date: Tue Jun 20 01:45:13 2023
Role: builder

This might be the date of the release.

When I log in, a window appears, and a few seconds later, zoom crashes.  The log file is long.  It contains the line:

X Error of failed request: BadWindow (invalid Window parameter)

What is the problem?





My Desktop computer dual boots into Debian 12 and Windows 10.

Zoom works fine on Windows 10.

In Debian 12, there are two Zoom bugs:

1. If I go to a Zoom test meeting, the test where I speak into the microphone
fails: Nothing is played back or it is played back weakly.

2. When I log into my Zoom account, a window appears with a spinning circle
saying "Loading your sidebar". In a few seconds, the window stops spinning
and Zoom crashes.

Following is the relevant part of "zoom_stdout_stderr.log". The whitespace has
been edited for readability.

I found a workaround for this issue
start zoom with `QT_QPA_PLATFORM=xcb`, and toggle off sidebar. after that you can run zoom with `QT_QPA_PLATFORM=wayland` and it will not crash untill you toggle the sidebar back 😃

This actually worked! Thanks a lot.

Works like a charm in Manjaro (Arch):
QT_QPA_PLATFORM=xcb /opt/zoom/ZoomLauncher
Disable the sidebar.
Launch zoom with QT_QPA_PLATFORM=xcb /opt/zoom/ZoomLauncher and then you can run zoom normally.

Super! For somewhat inexperienced admins (me) just would add that QT_QPA_PLATFORM is an environment variable which should be set to the indicated value when the launcher is invoked. Thanks for sharing this.

Thank you!


For those new to KDE, you can use the workaround on the Zoom shortcut in KDE's launcher.

  1. Activate the KDE Application Launcher and find the Zoom icon (fastest to type "zoom").
  2. Right click on the Zoom icon, and select Edit Application...
  3. On the Application tab, set Environment Variables to "QT_QPA_PLATFORM=xcb​" (without quotes). 
  4. Click OK, and start Zoom.

Note: I had to leave the environment variable set to "xcb".

This has stopped working as of 5.15.12. It worked earlier but not any more. 

Still works for me with updated KDE plasma, bookworm. Just fyi.

Thanks, I don't use Debian or KDE (Fedora, current release, and Gnome, current release), but I think the issue should mostly be the same.   Its Zoom and Wayland that are the issues.   I am looking desperately anywhere for hints to solve the problem which I am quite certain exists generally but so few people talk about. 


So, can you confirm, first  that if you start up any recent Zoom  verion in Wayland without making sure the side panel was hidden, that it will not start, and that it will start if you do hide the panel (by starting up Zoom in XWayland first)?


Second, that this specifically is true in the most recent Zoom  (  


I find that is is true in every other Zoom except this one.  I have went back and forth deleting all the settings, installing and reinstalled both 5.15.12 and 5.15.3 but hiding the panel only works with 5.15.3, and as I recall, earlier Zooms. 


Now, once you do start it in Wayland (any version of Zoom) and start scree sharing, how can you stop screen sharing?  Is it not the case that the screen sharing controls disappear after about ten seconds?  That is what invariably has happened for me, in multiple Zooms, multiple versions of Fedora, and multiple computers (one desktop, one laptop).   Totally uniform incorrect behavior on all these various platforms.   I have found a few others who agree but most people say nothing.  My opinion is that they think they are running Zoom under Wayland but actually it is running largely under XWayland and they don't realize it.



try to set disableCef=true in zommus.conf. Works for me in Debian Sid


Thanks, that works, but I wonder if it has any other downsides.  cef is, I believe, the Chromium Embedded  Framework.  I suppose it is used to render the calendar stuff in the sidiebar.   Hopefully not usued anywhere else. 


Still the issue is moot for me since under Wayland, the big problem has always been that once you start screen sharing, you cannot stop it because the controls disappear.   So I still have to run Zoom under XWayland.   


I assume you also cannot run Zoom totally under Wayland.


It should be SO EASY to fix this.  Just provide a keyboard shortcut to stop the screen sharing if you can't figure out how to keep the command toolbar visible.  Man.


1 Run "QT_QPA_PLATFORM=xcb zoom"
2 Click "Close Side Panel"

Is it possible to disable the Calendar using ~/.conf/zoomus.conf?
