Default Re: kwin: XRender "slow" (as usual), OpenGL much slower (new problem)

Can you check the PowerMizer state while this is occuring? I have noticed that when I have compositing turned on (and I normally don't, for exactly this reason) and PowerMizer has throttled down my card, the OpenGL performance for the compositor is very laggy.
