-- Information about the crash:
Hi KDE QA/Devs,
Since Plasma 6.5.3 (and now 6.5.4), I've noticed plasmashell crashes everytime
I resume from hibernate. In this case, I connected an external monitor during
the resume (which wasn't there while hibernating to disk).
Note that the stack traces were detected as not useful by Dr Konqi/Crash
Handler in 6.5.3 (it looked like a crash in a background polling thread with no
real code being executed), whereas in 6.5.4 we have something useful on the
failing thread this time.
Happy to try to repro more / test etc etc
Many thanks for the fixes & hard work!
Andrew
(P.S This was on a Dell XPS 9520 laptop with integrated intel graphics - Alder
Lake-P GT2)
The crash can be reproduced every time.
