Youtube videos really pixelated when resuming or fast forwarding

Since a day or 2 now, the youtube videos get Veeeery pixelated, it affects any video, when it should be looking like this http://puu.sh/87hD5.jpg it looks like this http://puu.sh/87hzs.jpg , It's VERY annoying, i already tried to disable all the extensions to no avail, and my graphics card should be able to handle material acceleration, and even when it's deactivated it continues anyway. (Gtx 660)
