-- Information about the crash:
So basically, whenever i press alt+tab to switch windows, my screen goes full
black, I see a line of random characters (@ if I remember correctly) and then
plasma restarts.
I just stumbled into this issue which seemed to occur every time I press
alt+tab, i'll have a look if it still repeats after rebooting and after pushing
this error.
If that's relevant, I had wallpaper engine installed, which is now removed as
it was causing issues (and caused a full system block yesterday). I am now
using picture of the day.
For extra context, I have two 4k screens, one 60hz the other 144hz on an nvidia
gpu with open source drivers.
The crash can be reproduced every time.
