SUMMARY IOTM background glitches out at random, seems to be tied to Teams, possibly other flatpaks too (however I haven't been able to reproduce it with Discord or Telegram so Teams seems the most likely trigger) Also seems to only happen in themes that support the 5.21 margins as I haven't seen this when using old themes that don't support the new margins (No foolproof way to reproduce it unfortunately, just some possible triggers and conditions to let the bug happen) STEPS TO REPRODUCE 1. 2. 3. OBSERVED RESULT check attachment EXPECTED RESULT SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 5.21.2 KDE Frameworks Version: 5.79.0 Qt Version: 5.15.2 ADDITIONAL INFORMATION
Created attachment 136477 [details] screenshot showing the glitch in action
Whoa, that is weird. Seems like a cache corruption issue. Does the issue disappear completely if you clear your plasma cache with `rm ~/.cache/plasma*`?

OK so compositing being enabled is a factor. That makes me suspect cache issues even more, since different SVGs are used depending on the compositing status. Please try clearing the plasma cache and restarting plasmashell the next time it happens. Thanks!

Just managed to reproduce it, turns it out's not related to compositing after all as I disabled the compositor and it's still there Wiping the cache didn't help either
Cool, thanks for the update. What kind of graphics hardware are you using?

Thanks. Are you using a non-default Plasma theme? Any other non-default settings at all?
(In reply to Nate Graham from comment #8) > Thanks. Are you using a non-default Plasma theme? Any other non-default > settings at all? added a sticky note and memory usage plasmoid, removed the show desktop plasmoid, and using a custom colorscheme, otherwise it's completely stock
New update: seems to happen pretty consistently on all but the first virtual desktop, meanwhile Teams seems to not be related with any of it, at least not anymore
