ApplicationNotResponding [ANR]: false
Qt Version: 6.10.1
Frameworks Version: 6.20.0
Operating System: Linux 6.18.0-xanmod1-1-edge-x64v3 x86_64
Windowing System: Wayland
Distribution: "Arch Linux"
DrKonqi: 6.5.4 [CoredumpBackend]

-- 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.
