Description Ralf Jung 2021-02-11 09:34:23 UTC

SUMMARY

When I "share my screen" in Firefox and select a minimized window, the screen freezes.

STEPS TO REPRODUCE
1. Join a Jitsi video conference (meet.jit.si) in Firefox.
2. Click "Share my screen", then select a window that is minimized.

OBSERVED RESULT

The screen freezes, but I can still talk to the other people in the conference. I can also move the cursor, but other than that interaction with the graphical session becomes impossible. I have to hard-reboot the system.


EXPECTED RESULT

Nothing I do in Firefox should lead to the entire session freezing like that.

Is it still an issue? I can't reproduce it because firefox doesn't let share minimized windows

I switched to wayland where screen sharing works very differently -- I just tried selecting a minimized window and it worked fine,
