A screenshot of the issue

Since as long as I am trying Plasma Wayland on a multi monitor setup, the background, and sometimes also part of the control panel, break after a while. It seems what keeps working is a rectangle of about the size of the smaller monitor. The rest "loses" rendering, and dragging a window over it etc. causes it to flicker wildly with artifacts of whatever moved over it.

The screenshot shows both screens as recorded by Spectacle.
