Noise On Screen

I do see the flash of scrambled graphics when going to console or 
shutting down, but this issue is not quite the same.  It only affects 
the top 10-20 lines of the screen, and the line colors changes as I move 
the mouse.  It looks as if random bytes are written to the screen 
whenever I move the mouse in any direction.  These lines will overwrite 
anything, including the top of windows.  The lines will not go away on 
their own.

If I start disable cupsd_enable in rc.conf, boot into gnome, and then 
start cups manually the line does not appear.  It only appears if cups 
is started before gnome loads... very odd :)
