I just wanted to share my story for users who have similar issues with the retina display "ghosting". I've read most of the relevant threads about this issue, and someone who had a similar story. I'm posting this here because the other threads seem to be getting a little noisy and off-topic. I got my Retina Macbook Pro about two weeks ago. I have been typically using it in clamshell mode with external monitors and hadn't noticed anything prior to yesterday. Last night I first noticed some ghosting when going to the dashboard to view a widget. The dark gray background made it easy to spot the ghosting caused from a website I was viewing on Chrome. I just did it again to show you an example of how it looks on my screen. Ironically I pulled up the flightaware website and left it tracking a flight for 10 minutes before taking the picture. Anways, on to my experience with Apple. Last night I setup an appointment at the genius bar for 11:15am today. I arrived and showed the genius what issue I was having and demonstrated it to him. He clearly saw it and understood the problem. Because my laptop had the 16GB of RAM upgrade, there was nothing he said that could be done from the store. He instructed me to call 1-800-MY-APPLE. I also asked him to make a support ticket to document what he saw and the issue in question. He never gave me a ticket number, and told me that "they" would be able to look it up when I call Apple. Ok, so I left. I called 1-800-MY-APPLE right when I left and really didn't know what department to ask for. First I asked for sales support and explained the rep my issue. He asked for a ticket number (which I was never given) and I told him that he should be able to look it up. He told me he couldn't look it up and would have to transfer me to another department. There I could provide my serial number, and then would get my ticket number, and then would be transfered back. Well a dozen phone calls later, and numerous dropped calls from Apple an hour went by before I finally got what I asked for. Anyways, I sit with this position. I have a new laptop in the "processing" state as if I just ordered it. Currently it's shipping in 3-4 weeks and delivers by Jul 30 - Aug 3. I have to send my current one back and just received the shipping label from FedEx for the laptop. It states that it needs to be returned by Jul 16. I plan on doing it sooner, but at least it gives a little time to still use the current one before shipping it out. That's my story, and I've attached some relevant pictures. Wish I would've never noticed it, but I'm the type of person who this would bug, while for others it may not be a huge deal. Hope someone finds this useful.
