Video driver is amdgpu.
More or less 9 times out 10, when monitor goes to powersave/sleep, when waking it up, plasmashell crashes. So it almost always crashes.
"Crash report" lets us send "automatic" crash report. So I've been sending them also.

Thanks, that's indeed helpful to do.

https://invent.kde.org/plasma/plasma-workspace/-/merge_requests/4238 *might* fix that, at least fixes it for the way i could reproduce (disabling internal monitor and enabling external in one go from the kcm) needs to see if it will make sentry reports go down

Pushed by mart into branch 'master'.

Fix redundantoutputs when the enabled screens change very quickly

on X11, when a single transaction from KScreen disables screenA and
enabled screenB, a new output order arrivers before the old output gets removed
 and in that moment the new screen will be considered redundant to che screen
that is about to be removed, causing an invalid internal state
