I've been running into this with ALL drivers on ALL operating systems, and do
not believe this is a software glitch. However, it may be something that you
are interested in, so I figured I would share it.
Basically, I have a 'silent' 8500GT:
VGA compatible controller: nVidia Corporation G86 [GeForce 8500 GT] (rev a1)
that has a tendency to deadlock and/or get 'glitchy'. When it get 'glitchy',
it just corrupts the screen. No errors anywhere, just the output gets random
blinking blocks etc. When it deadlocks, the system locks up shortly
there-after. I've been having this happen for maybe 18 months, but never
caught a stack trace or anything, so have never reported it.
Again, this happens under windows and linux.
Today I managed to catch some dmesg errors between the card crashing and the
system rebooting. here's the output:

I don't expect that this can be fixed, as even nvidia doesn't have it right in
their windows drivers, but I thought that might at least provide some feedback
on someone hitting a corner case in the error handling. ("PGRAPH_TRAP_TEXTURE -
no VM fault?" looks like an error message someone was expecting to be
impossible)
