Thanks for the hint.

Yes, my main laptop is running Intel hardware (X calls this "Mobile 4 Series 
Chipset Integrated Graphics Controller rev 7").

However, I've also seen the same type of corruption on a desktop (nVidia 
running a recent git nouveau drivers) and on another (old) laptop (ATI Radeon 
Mobility [something]).  So, I'm surprised that a hardware driver update fixed 
the problem (you're sure none of the X client libraries or server-side 
components were also updated, right?).

I'm running 2.6.29 kernel on these machines, so perhaps it might be fallout 
from this mode-switching support in the kernel (although that's wild 
speculation).

Anyway, I'm currently on a business trip so I'd rather not fiddle too much as I 
need the laptop to be functional (albeit, with a slightly annoying problem).  
I'll try to look into the upgrade when I'm back.

Cheers,

Paul.
