This is a synchronisation problem. Essentially, the system is mid way
through updating the graphics buffer at the point it's pushed out to the
screen. Enabling OpenGL vsync seems to help with this (I've not had it
enabled for long so I can't be certain on this - with previous drivers
enabling this option totally messed up the display, so I've only just
got around to retrying it).
