It might be a driver issue. I use Intel GM45 hardware myself, have
confirmed excellent performance on a couple of GeForce cards, but have
also heard reports of visual artaefacts on some Intel machines -
possibly due to driver problems.

If you have a digital camera which can record video, can you send a
short clip of the problem occuring to me? (I presume it may be difficult
to screen-shot, but give that a try too).
