I get this sometimes on intel as well. A click on the desktop (triggers refresh) usually fixes. Most likely related to the KWin patch, therefore we should target a fix for 8.10 (or rather have to, considering that this doesn't happen with stock 4.1.2).
Nice fact is that I don't use 3D effects which make this regression a lot more annoying.
