Default Re: VDPAU and KDE 4.8 compositing = slow

Flash does what it does because it needs to postprocess RGB data and Xv for instance uses YUV, although I'm not saying Flash is the best piece of SW out there.

When I switch to Compiz, a lot of (if not all) my VDPAU problems (crashes on FS->window->FS toggling, high CPU load, ...) instantly disappear, so I believe that KWin is doing something wrong which causes VDPAU to malfunction. If you'd like to raise a bug report on KDE bugzilla, I'd be happy to contribute with my findings.
