Description Gabriel 2021-12-11 10:16:25 UTC

Application: plasmashell (5.23.4)

Qt Version: 5.15.3
Frameworks Version: 5.88.0
Operating System: Linux 5.11.0-41-generic x86_64
Windowing System: X11
Distribution: KDE neon User - Plasma 25th Anniversary Edition
DrKonqi: 5.23.4 [KCrashBackend]

-- Information about the crash:
- What I was doing when the application crashed:
I had just opened Discover and made a search. At the same time as the update notifier triggered, I was clicking on a program in the task manager to see an update in it. That's when Plasmashell crashed for me.

I hope any of these bits of information are relevant and helpful. Feel free to ask anything and I'll try my best.

The reporter is unsure if this crash is reproducible.

DrKonqi auto-attaching complete backtrace.

Seems graphics-related, not sure what to do with this one.

Comment 3 Gabriel 2021-12-15 01:15:04 UTC

Whelp, if that is the case then it might be because of Nvidia. If so, then maybe there's not much that could be done about it. :^/

No. It's in QSG, which is a layer above graphics.

We vaguely know. The wallpaper object gets moved between windows, but because it's parented to both the containment but not properly it gets in a mess.

No. It's in QSG, which is a layer above graphics.

It'll be some graphics nodes being not cleared up by the scene graph correctly for some reason. We had a theory for wallpapers, but your triggering symptoms don't quite add up with that.

Second crash log

Not sure if it is useful, but a similar crash occurred again a week ago. I saved the crash log to share here. Discover was not involved. Plasmashell did restart itself, but went down completely about an hour later, leaving only my open windows visible. I can't say what caused it.
