SUMMARY
Recently switched to an AMD GPU (fresh install of CachyOS), and i'm noticing after waking from sleep the desktop wallpaper will get graphical glitches in random locations, anywhere from one to a dozen. (Screenshot attached). It stays with the wallpaper regardless of desktop chosen, selecting a new wallpaper and going back resolves the issue.

STEPS TO REPRODUCE
1. Wake system from sleep
2. Login

OBSERVED RESULT
Graphical glitches on wallpaper

EXPECTED RESULT
No glitches

Thanks for the bug report. Graphical glitches like this are usually due to the driver. Can you report this to the AMD folks here?
