Anyone else having issues with this and KWin? On Arch, I have 4.11RC2 and after installed the beta drivers the corners of my windows disappear some times (basicaly the min/max/close buttons on the right, and the app icon/stick button on the left). I also noticed that on sometimes the shadow/glowing border thing around a window may only render on the top/bottom (and around the corner), but the sides would be missing it. I have it pretty much on default - openGL 2.0, QT Raster, 'Accurate' for the scale method and VSYNC set to automatic (this seems new in 4.11).
No announcement yet.
