I have just noticed that my screen on my rMBP does this exact same thing as this video: http://www.youtube.com/watch?v=A-0oGizc0fw and it only happens when I'm going through images on Facebook. Is this a software related issue or what is it? I bought this computer 3 weeks ago so I will take it for a repair if it's hardware. Thanks! ---------- By the way I checked and my screen is a samsung screen.
