Bug description:
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.
