SUMMARY

I just resumed my KDE - Wayland desktop back from sleep.
I am familiar with the usual one screen stays black while the other one works
thing and sometimes no monitor comes back at all.
But this time I experienced a new sort of bug: I was able to log in, both
screens were active.
However, on the primary screen, a part of the background stayed black and the
was extremely flickering when I moved my mouse cursor.
I managed to capture a video with my phone - I should definitely say  there is
an epilepsy warning!
You can find the video here (too large for the uploads):

3.

The background should not start to flicker.
