I learned from Genius at apple store days ago 1) "see, while we are talking, it is less than 5 minutes the ghosts disappeared, so this is not a hardware issue" 2) "this will happen under certain condition, so it is not a hardware issue" 3) "If we replaced the screen, what about it happened again?" Happend at the time I wanted to replace the screen (second time). Please check the full story here http://www.facebook.com/ImageRetentionOnRetinaMacbookPro For now, the only option to me is wait till apple release kinda UPDATE TO FIX THE PROBLEM. I or we (who got or may have the same situation with me) need your help! THANKS!
