KDE Plasma6, Wayland, intel gpu, graphical bugs, Endeavour OS/arch based

Having some weird random graphical artifacts with Plasma 6 on arch based- Endeavour OS running on an intel gpu.

My guess some kind of redraw/refresh bug with plasma on wayland. It’s not present on xorg.

The big white area is actually transparent/ blank alpha when captured with spectacle. When present nothing gets drawn in that area anymore. Sometimes you can revover to normal by invoking the overview effect and get back to desktop. Sometimes it sticks and only reboot/restarting the DE helps.
