Do you have flipping turned off? That's quite a common cause for problems.

While we're talking about display issues, there is a problem with how blender 
deals with rendering the cross hairs or circle used in the selection modes. 
(triggered by the "B" key")

The cross hairs or circle do not display unless the mouse button is pressed. 
This has something to do with using a 3D rendered desktop (compiz). It 
normally uses a double buffering where all window changes are rendered to 
offscreen pixmaps. When blender is in full screen mode this is not a problem 
because compiz allows fullscreen programs to bypass the offscreen pixmaps and 
render directly. Not sure why these would not be drawn to the offscreen
