Problems with Safari 4, scrolling and the colors of the page

Just right after the keynode I installed Safari 4 on my Mac. I've allready tested the beta for a cupple of weeks and was surprised about the speed. But after the the installation of the final release I recognized, that the color was fading while scrolling. In the worst case I got a black/white page. This problem is posted in an Apple Support Discussion.

The solution provided in the discussion seams to work for me.

If you'll get this problem, open Disk-Utility app, select your HD and press Restoring Permissions. Wait some minutes, restart Safari and that's it.
