Lightroom 3, scrolling and tearing

I have noticed this issue with Lightroom 3 for quite some time and its quite painful bug. The following video demonstrates the problem.

I have reinstalled my PC, using the latest video drivers and even tried to simulate a solid state disk for the hard drive (via a RAM Disk). While the RAM disk helped the tearing problem was still there. Wish I had a fix for this. It makes scrolling through my pictures quite painful.
