Comment 3 for bug 479375

To rule out some further things:
- It does not make a difference if the 3D effects are turned on or off
- I does not make a difference if the proprietary nvidia driver is used or not

I guess the most important thing right now would be to find out if this is actually a process scheduling problem or a problem in the hda-intel driver. But I have run out of ideas how to find out about that...

Thanks for any help, Alex
