--- Comment #9 from gav...@gmail.com ---
Hi all! It appears i'm having the same issue and it's quite bad, i have to
avoid alt-tabbing altogether just to avoid it. Crash Handler however made a
backtrace that i'll attach as kde6_alttab_crash_gavlig.txt. Also the repro is
quite easy for me: 
- open an gpu intensive application (in my case it's a Bevy Engine app i'm
woring on, it get's rendered via Vulkan, but it can also be firefox rendering
some youtube videos for example) 
- start spamming alt-tab
- sometimes it crashes right away, sometimes you need to do it 2-3 times.

(if my backtrace is lacking something, i'm ready to get more info, just let me
know)

here is my system info:
