Question: fullscreen youtube issues
I have a 2015 macbook pro 15in retina, and whenever I go fullscreen on a youtube video, it shows a white screen with a black box. If I move my mouse it plays the video normally, but as soon as I stop, it shows a white screen with a black box in the upper left corner again.
Also some webpages I visit, every time I click on an icon, the screen will flash black.
I've found a couple people online with the same youtube issue, but no one seems to have an answer yet.
MacBook Pro (Retina, 15-inch, Mid 2015), iOS 8.4.1
