So I've had my rMBP for about a week now, and I've noticed that my screen would flicker whenever I am downloading something. It would flicker for about a second every 30 seconds or so. It stops when nothing is downloading, but it is getting pretty annoying and I'm wondering if I should call Apple up and ask for a replacement. Is anybody else having a similar problem? ---------- OK so I am running Skype for the first time on my rMBP and I am also getting the flickering. I guess it happens when I have multiple programs running.
