> Do you have flipping turned off?

Where do I find the flipping option? Is it a OpenGL driver option? 
I don't have a flipping option in the nVidia control panel, just a quad
buffer enable/disable option. If I disable quad buffer, Blender displays
correctly but I can't run games in stereo at the same time. The idea is
to have quad buffer enabled all the time but still being able to use
Blender normally. 
I don't have a problem with the cross-hair in Windows when quad buffer
is enabled, I just have all the menus and dynamic panels flickering like

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

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

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