https://youtu.be/eBWM7MeuLEk https://youtu.be/XIAno8r5UTs What helps is to close/reopen window or restart kwin what doesn't help (only temporary refreshes the content): - minimizing - resizing - doing some action on some elements that trigger refresh Drivers: MESA & NVIDIA prop. OS: Arch up-to-date Timeframe: it happens for at least as long as I use Plasma (maybe a year now), on every PC I have (All Arch Plasma). Rendering backend: OpenGL 3.1 Custom settings: Enabled some desktop effects like Fade, Wobbly Windows (also, Wobbly Windows randomly show flickering artefacts in places animation took place but no longer is taking place as long as you hold the window), plasmashell (as it constantly refresh time in seconds). When does it show .. after few days while running a window with high refresh rate like Audacious (with constantly moving text in window), or older pavcontrol (as there sound level bar), or chrome. Less often (or at least i didn't saw this problem) on windows with less refresh rate like terminal, dolphin.

Maybe related to: https://bugs.kde.org/show_bug.cgi?id=335330 I will try: export KWIN_TRIPLE_BUFFER=1 and report back if i see flickering (normally it takes few days to start flickering).

and the mesa system?
Workstation (laptop) with mesa (nvidia disabled): On the system with mesa i did run export KWIN_TRIPLE_BUFFER=1; kstart kwin_x11 --replace and as for now no artefacts I didn't reset theme/compositor on MESA (laptop) as it's my workstation that I could not affort to get a downtime for last few weeks, next week i will upgrade also my laptop and will try there too, but until new plasma doesn't have a fix i assume it will be exactly the same ---- Workstation with nvidia only: i did also use tripple for short period, no errors noticed, today upgraded nvidia station to plasmashell 5.12.5 and running without tripple buffering, time will tell ---- I saw the simple way to leave a PC working with Audacious (with "winamp" skin) for a few days, audacious continuously scroll the track name from left to right forcing refresh/render that triggers the bug, other app show the same problem but at longer time (as they refresh less frequently) Also maybe it happens when i have workstation locked, hard to tell. ----- AKA: tripple bufforing somehow helps MESA: not done anything NVIDIA: no change on theme/compositor reset
just experienced this bug on 5.12.5 and running default without tripple buffering - with one window of firefox
plasmashell 5.13.1 Funny behaviour as it refreshes around other windows :) https://youtu.be/bTASAx0jbpU (on NVIDIA graphic / nvidia driver) On Intel/mesa - OS still not up-to-date because of missing a way to run a outdated necessary app with newest libraries, so probably one more week until it gets sorted out ready to update.
