I don't know if this patch is the cause or not, but video rendering is very bad after I applied this patch.
Everything else looks really smoother, but regarding playing video files, a movie that I could see in a pretty good condition before applying this patch is now very,very,very, very, very bad. Sound is good but video is framedropping like there was no tomorow, it turned like it was a stopmotion movie...
Can someone confirm?
