Screen recording of the problem
SUMMARY
On my primary monitor (AOC CU34V5CW/BK connected with USB-C, to a Lenovo
AMD4700U laptop running Fedora 38 with KDE) after some time since system
restart visual artefacts are starting to show. This is visible as very fast
flickering of parts of the screen (only where there are no windows shown). As
soon as a window is covering the desktop, the flickering is gone, when the
window is hidden (for instance minimized) the flickering comes back.
STEPS TO REPRODUCE
1. I can't find a specific step to reproduce, this starts happening randomly
after a period of activity (1+ hour since restart)
OBSERVED RESULT
Flickering parts of the screen
EXPECTED RESULT
No flicker

Linux/KDE Plasma: KDE 5.27.6, KDE Framworks 5.108.0, QT: 5.15.10, Kernel 6.4.6,
System Fedora 38
