App window freezes at Zoom Video Conferences

User Support

Since migrating from Qubes 4.1 to 4.2 I experience occasional app window freezes when I use the video conference software zoom.

Further information

  • This behavior seams to be rather unrelated to overall system resources usage.
  • Not having any webcam or microphone connected to the zoom vm does not seam to have any impact either.
  • I use the debian-12-xfce template as a basis for my disposable zoom vms template.
  • The issues remains the same for at least the last three zoom versions.
  • Killing zoom and restarting it works. No vm shutdown is required.

Can anybody second this issues or has be can even able to solve it?

Just had some lengthy zoom conferences the other day without any such issues using a disposable based on debian-12 (gnome) on Qubes 4.2.

After some playing around for the last weeks I found the cause of my issue.

Deactivating the TearFree option in /etc/X11/xorg.d/20-intel.conf solved it for me.

Section "Device"
        Identifier "Intel Graphics"
        Driver "Intel"
        Option "TearFree" "false"
EndSection

There could be some issues with Intel driver:
