Hello all. I've had a rMBP since October and I absolutely love it! I've had a few issues lately that I'm not sure are common or not. I've searched and really can't seem to find much on the topic, but I do apologize if these are issues that have been addressed previously. Mostly, images (scrolling) tend to flicker and text (scrolling) also does the same. It drives me crazy! Irritating to say the least. But also, often times when I open the notebook, the screen goes black and then flickers. And lastly, my wallpaper resets when I reboot the computer. All these issues are more clear in the video I compiled today. My point is, are these "normal" issues? Or would Apple be able to service my computer to remedy the problems? Thanks in advance guys!
