-- Information about the crash:
Immediately before this crash the entire screen blanked / flashed with blank
and green left and right halfs of the screen.
This occured while browsing/scrolling a static web page with no video content
or multimedia, on Firefox (flatpak) 140.0.4
After the flash this crash report was generated for plasmashell. Restarting
plasmashell was succesful.
Exact same flash of green an black occured earlier on the same day when
shutting down the machine, but no other effects could be observed as the
machine continued shutting down.
These effects occured only after switching to Plasma Wayland. Such effects have
never occured on X11.
The crash can be reproduced sometimes.
