Is anyone else having this problem?.. I've gone through two rMBP's (this one being my second one) and the first one was a dead pixel, and then soon found out that it also had a bad battery. Was advised to return the computer and get a new one.. Now I'm on my second one, and was just having a grand time until the screen started to flicker.. I would take a screenshot if I could but it decides to do it when it wants too. The only example I can really give of this would be the fact that the MacRumors logo is ending up in the middle of the screen.. I must note a few things though I haven't ran a diagnostic on that computer yet. I should, but it's stupid late and I work tomorrow. I usually am on a website that shows a lot of GIF files, don't know if that could be a problem. The OS is up to date, and all updates are installed. And flickering seems to match with my typing.. If I leave it alone, it will do it on it's own.. But not as often. I'm wondering if anyone else is having the same issue (And a possible solution would be really nice but I'm thinking taking it to the Apple store is my best bet.). I don't know if having my computer running on my battery is the problem.. But it's been on the battery only before, and it worked fine a day or two ago.. Next day it does this.. I'm seriously starting to get sick and tired of stuff like this happening to my almost 4K machine.. I need this bad boy for school, and the fact that there is very little problems with it but all seem to be larger than average problems.. But I demand perfection for something that I am paying off for the next 4 years of my life.. It's kinda pissing me off..
