SUMMARY Tearing happens often on AMD Renoir and it demonstrates itself in a weird way when panel listed apps start to jump around pixels and flashing. Then some windows won't be properly rendered and they need to be either minimized and opened again or closed (killed) to work correctly again (e.g. Firefox often). STEPS TO REPRODUCE 1. Not sure, intermittent issues, random times OBSERVED RESULT Tearing, windows not displayed correctly, e.g. blank or empty EXPECTED RESULT Correct display, no panel tearing issues SOFTWARE/OS VERSIONS Operating System: KDE neon 5.25 KDE Plasma Version: 5.25.5 KDE Frameworks Version: 5.98.0 Qt Version: 5.15.6 Kernel Version: 5.15.0-46-generic (64-bit) Graphics Platform: X11 Processors: 16 × AMD Ryzen 7 4800H with Radeon Graphics Memory: 30,8 GiB of RAM Graphics Processor: AMD RENOIR Product Name: PROX14-AMD
Can you check what mesa version your distro ships?

I am on Ubuntu Focal and an AMD GPU, too, and I experienced similar glitches (horrible tearing when moving windows, etc) but today those issues are gone again.
This vaguely sounds like https://gitlab.freedesktop.org/mesa/mesa/-/issues/7352
(In reply to Nicolas Fella from comment #4) > This vaguely sounds like > https://gitlab.freedesktop.org/mesa/mesa/-/issues/7352 Yes, it sounds similar. Although tearing usually happens only around panel for me, basically it makes panel tasks jumping around in a weird way.
