Comment 16 for bug 340578

Well, I'm now running 2.6.30-rc7 + (from xorg-edgers) intel 2.7.99 + mesa 7.5 + latest libdrm on 965G (GMA X3100) and having compiz vblank enabled still makes things crawl. So I don't think the upstream has solved it. If you happen to read this and can reproduce, this bug could be retargeted to eg. xserver-xorg-video-intel. It's quite intolerable if people bump into this problem accidentally (running metacity --replace is not in everyone's common knowledge).
