Recently - in the past 24 hours - Safari has been misbehaving. The issue is with playing video. Specifically, on Netflix. I first noticed it yesterday. The video is choppy, pixelated/blocky, and the colour even distorts to green at irregular, yet consistent, intervals. It only seems to do this on Netflix - YouTube works great and I've had no issues with it. I have tried Netflix on Chrome and the video plays smooth as butter on Chrome. So what's up with Safari? I did, yesterday, install AdBlock Pro (I already have AdBlock) but I think this was after the issues arose. Also, since the issues arose, I have disabled both extensions so I doubt they are what is causing this. I have restarted my MacBook Pro and even reinstalled adobe flash player to see if that made a difference - it didn't. http://postimg.org/image/yavblk7w5/ http://postimg.org/image/4k86zsmwl/ http://postimg.org/image/lysf82k1h/ I hope you are able to view those pictures I have taken. In them you can see what I mean by the blocky, pixelated view, as well as the occasional green glitchy parts. It's also worth mentioning that my internet speed is NOT the issue here. You likely can't tell from those images, but Netflix is successfully streaming in 1080p. It's just that the 1080p seems to glitch and it goes all funny. Also, the video is NOT merely buffering. The audio plays on smoothly in the background, the video is just interrupted, then it'll resume clear as day, then it'll do the same thing. It varies as to how severe the distortion is as well, some are little things, others are extreme (e.g. compare the first/second picture to the third one). Also I thought I'd try uninstalling and reinstalling Silverlight. It seemed to work for about 2/3 minutes then it happened again. Still no fix. I even did the 'Develop' thing where you switch to an older version of Safari and that didn't work. Please help! This is incredibly frustrating. I read somewhere that Netflix uses HTML5...could this have something to do with it?
