Yes, still present in latest stable 2.6.28.5

I updated the report to say that this happened on my 5 year old Pentium 4, but now I got a new Dell desktop (Intel G45 based) and the exact same problem happens, so I can't be the only one seeing it. In the bugzilla Eric Anholt said that it could be related to vblank and that jbarnes had look into a similar issue before, so maybe he has some clue.

Thanks.
