Comment 0 for bug 1575412

When launching certain OpenGL games, graphical glitches consisting of current or recently closed applications can be seen at the very bottom of the screen as the window goes fullscreen.

This mostly only happens on games that load a lot of data before starting. Smaller games usually start with little or not graphical glitches.
