Hello! I bought a 2014 rMBP about a month ago and I really love it. I haven't had any display issues that I've noticed, but I'm not very picky to begin with. Today while watching a video on full screen I noticed some image retention in the corner of my display where my Twitter feed always sits. It's not particularly noticeable though now that I HAVE noticed it, it's a tad distracting. I'm not all that bothered, but I was wondering if this is something that goes away after a period of time. Since my Twitter feed is basically always staying in the same spot, it doesn't bother me too much if it starts to faintly retain the image, but if I were to move it for a few hours would it go away? Or is this a permanent thing?
