SUMMARY After a day or so of starting the KDE session on X11, windows will start partially updating as shown in the linked video. Toggling the compositor on and off (ALT + SHIFT + F12) will temporarily fix it, but after a few minutes it will happen to the same window, or another window, or even the panel. Replacing kwin_x11 or plasmashell doesn't fix it. The video was captured a month ago, I've just been to lazy to post it here. But it still happens as of 5.25.5. I think it started after 5.25. Not sure if suspend is involved as I constantly suspend my system. STEPS TO REPRODUCE 1. Login to a KDE X11 session for a day 2. Windows, and even the plasma status bar will randomly partially update OBSERVED RESULT Windows fully update EXPECTED RESULT Windows partially update SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 5.25.5 KDE Frameworks Version: 5.98.0 Qt Version: 5.15.6 Kernel Version: 5.19.7-zen2-1-zen (64-bit) Graphics Platform: X11 Processors: 12 × AMD Ryzen 5 5600X 6-Core Processor Memory: 62.7 GiB of RAM Graphics Processor: AMD Radeon RX 550 / 550 Series Manufacturer: Gigabyte Technology Co., Ltd.
