SUMMARY
STEPS TO REPRODUCE
1. Switch taskbar to icons mode (where only icons shown, without program name).
2. Make sure that window preview enabled
3. Hovering mouse over tasks switch windows with alt+tab. Over some time (for
me like average 30 minutes) whole plasmashell will freeze (type of bug similar
to endless I/O wait, meaning no high cpu load, just stopped process with only
option to fix run kill with flag -9, as without flag no effect.). Then it keeps
killing plasma shell for approx 7-8 seconds and reloads plasmashell. After
reload no more window previews show, only huge icon drawn and since that
plasmashell no longer hangs until system rebooted and previews shown again.
Also less critical bug is, that if to hover mouse so that preview appears and
then switch to full screen window preview gets stuck until window don't exit
full screen mode or minimized.
SOFTWARE/OS VERSIONS
Windows:
macOS:
Linux/KDE Plasma: Latest

KDE Plasma Version: 6.1.1

ADDITIONAL INFORMATION
Guess that matters, it's Wayland session (this definitely matters), but also
new nvidia driver as well. That's the only bug remaining so far that is
critical to fix I found that really causes a lot of inconvenience. If to
disable previews of windows, no hangs happen and stalled image artifacts
happening.
