Comment 18 for bug 676413

Strange. I tried my workaround again today and it did not work as expected. No performance change after changing the scheduling policy of X. Then I tried to also set it for compiz, and suddenly everything was smooth again. But then I changed it back for compiz, still everything fine. And now the changing back and forth for X had again the effect described in my previous post.

So for me it seems as if something with the scheduling gets completely messed up...
