+ I'm running Ubuntu 12.10 inside a VirtualBox 4.2RC2 VM, and Ubuntu doesn't 
recognise the 3d drivers so it is falling back to llvmpipe.
  
  When I move the mouse around, it sometimes vanishes completely, and
  sometimes jumps over to the left or top left of the screen. If I'm
  moving a window with the mouse at the time, the window vanishes or jumps
  over to the left or top left as well.
  
  With 'force complete redraw on initial damage' turned on, it seems that
  glitch happens much more frequently.
