The crash before the crash

Description Victor B. Gonzalez 2024-08-30 18:17:14 UTC
Application: plasmashell (6.1.4)

Qt Version: 6.7.2
Frameworks Version: 6.5.0
Operating System: Linux 6.10.6-zen1-1-zen x86_64
Windowing System: X11
Distribution: "Arch Linux"
DrKonqi: 6.1.4 [CoredumpBackend]

-- Information about the crash:
I've made a habit of checking `journalctl -xb -r --priority=err` immediately after logging in. Today I see `(plasmashell) of user 1000 dumped core` twice (back-to-back with a difference of 6 minutes). I'm only here because I've decided to put the `plasmshell - Crash Handler` to use. If it means anything, this happens quite often (also with sddm-greeter) but today I've decided to upload it.

The crash can be reproduced sometimes.

The crash before the crash

This crash happened 6 minutes before the reported crash. Also, I did not see `plasmashell` restart before my eyes (it recovered perfectly?) and the only problem I could visually see on was my main monitor had some visual disruption to it (flashing pixelated bars randomly jumping around every other second or so). Other than this, it was simply a minor annoyance and it didn't seem to break anything of importance.
