--- Comment #1 from hayarms@gmail.com 2011-06-08 00:45:17 --- It happens to me too, and I think it happens to everyone.
It is a very well known bug.
As a temporary workaround I use the profile power_method with the low profile. It doesn't hurt the performance of my desktop even when using composinting and I can always set to "high" the card with a script when I need more power (like running heavy 3d programs). Anyway, I have a 5850 card, so people with a lower end card may not find the low profile suitable for them.
