Description p d 2022-10-16 19:30:57 UTC

SUMMARY
If xdg-desktop-portal-gnome is installed and running (and it is by default on Fedora 36): Since KDE 5.26, using OBS or screen sharing causes the KDE session to crash and restart (tested in Wayland), and removing xdg-desktop-portal-gnome fixes this.

STEPS TO REPRODUCE
1. Be on Fedora 36 KDE with wayland session
2. Have xdg-desktop-portal-gnome installed and running (it is by default)
3. Try to screen share in telegram or screen record in OBS
4. Instant crash

OBSERVED RESULT

Kwin crash when sharing / recording screen

EXPECTED RESULT

There to be no crash.

I upgraded to Fedora 37 KDE with KDE 5.26 from the kdesig copr and now it seems to crash for a different reason (when attempting to record screen in OBS on Wayland):
