Description rjx_ 2024-04-19 16:13:23 UTC

Application: plasmashell (6.0.4)

Qt Version: 6.7.0
Frameworks Version: 6.1.0
Operating System: Linux 6.8.7-zen1-1-zen x86_64
Windowing System: Wayland
Distribution: Arch Linux
DrKonqi: 6.0.4 [CoredumpBackend]

-- Information about the crash:
It's an old bug (being there at least since plasma 5 days), but slightly difficult to trigger:
you need an app to have an animated tray icon (or maybe just changing state/bitmap?) being triggered while the screen is locked (and/or potentially even turned off - at least i had an easier time reproducing when my monitor was turned off completely via h/w button).

Reproduced with Konversation and people highlighting my nick.
I am on Wayland, but i encountered this bug on X11 quite some time ago too so it's probably unrelated to that.

The crash can be reproduced every time.

Now come to think of it, this could be

Comment 3 rjx_ 2024-05-16 18:02:01 UTC

Now come to think of it, it's very likely a notification (popup), not a tray icon animation, which is most likely tied to the crash, as i think some apps did not have any tray animation/icon change but still crashed when a notification appeared on a locked session.
Still most easily reproduced with a turned off monitor, in my experience at least.
