--- Comment #2 from and_...@hotmail.com --- I have tried to update to the Nvidia beta drivers (450.1) and the problem still persists (I was previously using the stable 440 drivers). This is very likely a bug in how KWin handles Wine window buffers. Is there something I can do to try to fix this bug? Changing the backend of the compositor (XRender or OpenGL) has no effect. -- You are receiving this mail because: You are watching all bug changes.
