Hi there,

I had the same "problem" too. 
The problem was that the guest machine was using incorrect refresh
rates, probably because it was using default/failsafe/conservative
settings, or virtualbox was emulating a substandard monitor, do'nt know.

Cure: simply edit /etc/X11/xorg.conf in the Ubuntu virtual machine, so
as to explicitely specify the correct refresh rates for your monitor.
