-- 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.
