Description jinwk00 2024-03-14 12:15:58 UTC
SUMMARY
***
Every time when Task switcher (Compact) is opened while having some Xwayland or WINE applications, the entire shell freezes for random amount of time, whether if it is opening or closing. The issue persists even after those applications, until I restart SDDM or plasmashell. Once there was an entire freeze on the plasmashell, had to kill user through SSH
***


STEPS TO REPRODUCE
1. Have several Xwayland and WINE applications opened
2. Optional: Let the device sleep 
3. Open task switcher, let it close, observe the freeze

OBSERVED RESULT
Shell gets frozen for random amount of time

EXPECTED RESULT
It should be opening and closing right away

Can you clarify which part you mean by "shell" does the mouse move?
