Hello again, Does anyone know why some FPS games tend to have the screen slide sideways occasionally, showing part of the desktop (this is a dual display system so my desktop is 2048x768). I've configured the metamode settings in xorg.conf to blank the primary monitor when the games go full screen and change the resolution -- which works fine except when the mouse movement causes the screen to slide around showing the desktop.
