Hello, I just test your branch, it breaks the 3 apps I tested : - glxgears, I do not see gears. I can see them quickly by moving the window at the border of my screen - nexuiz-sdl : the menu is break. (not tested ingame) - etqw : the menu is break too. In game, I have "phantom" frame. This is hard to describe, and I have no screenshots to show you exactly. To sum up, I have the impression that the frames are mixed. I will test your future patches (if any).
