After a hint on IRC I tried changing graphics drivers.
It would seem that the bug disappears if I load the restricted graphics drivers for my NVIDIA G70 [GeForce Go 7600].
So, the bug appears with the un-restricted driver and not with the restricted ones.
Hope this helps you all produce a fix to this bug.
