--- Comment #7 from Marios <marst...@gmail.com> --- Ah, I think I have some additional info. When I said sometimes it just stays black, it seems that that was because the mouse was moving. In fact, I've found out that it starts flashing as the mouse is moving, and stops flashing and will either stay on background, or black screen, as the mouse move stops. It is still solved by force showing the desktop with Meta + D. As a game developer I'm taking a guess here and saying that it might be a frame buffer issue, with one of the framebuffers not being updated with the desktop background - probably because of vsync? -- You are receiving this mail because: You are watching all bug changes.
