KDE Frameworks Version: 6.8.0

If I disable the black screen through "Dispaly Configuration" and the re-enable it, it works normally.

Could be more general bug isn't specific to a two-monitor setup: https://bugs.kde.org/show_bug.cgi?id=497204

In my case the error occurs during normal work, non after screen unlock, at least not immediatly after screen unlock
Comment 3 Nate Graham 2024-12-11 21:13:00 UTC 
Sounds a bit like Bug 496923. Does it reproduce on Wayland, or is it X11-specific? I know you said you're not using Wayland because you need to use AnyDesk, but can you test it out for a little while anyway? No need to permanently switch.

I looked better and indeed the problem always occurs after a screen unlock and occasionally during normal operation.

I tested with Wayland for two days and the problem never occurs. So it seems that is specific to X11.
