Pixelated YouTube?

I have a question for everyone, is your html 5 youtube in chrome pixelated? Mine is and I can't seem to figure out what is causing it. I'm considering it might be Nvidia Beta Driver 337.50 but I wan't to know if anyone else has had this problem lately and I am trying to rule out other possible causes, such as chrome. 


If anyone knows how to fix this I would be much appreciated, closing chrome and reopening it fixes it for a while but then it comes back after a video or two. 

It's not reverting to a lower resolution video right?

No, however even when set to 1080p the internal resolution at full screen is stuck at 360p.

have you tried the beta or developer edition of chrome... also an extension could be messing with it
