I'm flogging dead horse, the 1600x1200 desktop will obviously allocate a
lot more card memory, and leave less memory available for textures. And
with less memory for textures, you need to swap them from main memory more
often.
So if the texmem code doesn't serialize the swapping with the usage, you'd
see the texture being replaced by a new one potentially before it had
actually been rendered and was still in the command queue. Resulting in
flickering.
