This is completely mystifying, since NM doesn't touch the display screen at all, 
nor does it touch X...  I've never seen anything like this.  The most likely 
explanation that I can think of is that your hardware or drivers are odd, 
possibly that there are bugs in the kernel drivers for your hardware that stomp 
on X memory during certain operations...  What are the specifics on your laptop?  
Perhaps the output of 'lspci' from a terminal would shed some light on that.  I 
can't think of a technical reason beyond that which would cause X to have 
graphical glitches.
