Yes, I get something like a single frame being drawn 'offset' so it starts perhaps halfway down the screen and completely misaligned. One program I ran the other day did it regularly.
As FastM says, turning VSync on seems to make the problem disappear. The 30.83 drivers don't exhibit this, in fact I'll make this statement:
The 40.41 drivers are faster than the 30.83 drivers, but are not as 'smooth'. Try playing UT2003 demo with both and you'll see what I mean.
