--- Comment #3 from Michel Dänzer michel@daenzer.net --- (In reply to comment #1)
After quick bisecting, it looks like commit "radeonsi: Use dma_copy when possible for si_blit." (5d5c20920e0e570742a497aa047e99a2fa3c04f2) is responsible for that.
See bug 80787.
When reverted, the full screen corruptions disappear, but window menu corruptions still persist.
The kwin menu corruption is most likely a glamor bug. You can work around it by selecting 'Raster' for the rendering engine in the kwin advanced desktop effect preferences.
