I am on Ubuntu 18.04.4 LTS running i3wm.

I frequently use Zoom for meetings in the current pandemic situation and am able to use its screensharing facilities during meetings. However, as soon as someone (either a participant or I) attempts to annotate something on my screen that is being shared, the window manager crashes and blacks out. Then no one is able to see anything on my screen (including me). I can get a terminal using Ctrl-Alt-FX combination but have not able to get the window manager restarted. Usually I then have to restart my machine.

This problem does not happen if I am using the normal GNOME window manager (available as a choice when logging in). Has anyone else experienced this problem or can suggest a fix? I would really like to continue using i3wm when starting a Zoom meeting rather than having to log-out and in each time I need to attend a meeting.

Not on ubuntu (Enterprise Linux), but I was having issues with the annotations if I didn't have a compositor running.

I used zoom's support article to run with their recommended settings with compton instead of xcompgr and it seemed to fix the annotation issue.

Unfortunately I still have an issue where my screen sharing will randomly freeze. One problem at a time.

  • That works for my EXWM as well. The only drawback is that I don't see the annotation panel so I can't clear the annotations afterward. Still much better than a black screen
