long story short, my first retina kept having consistent issues with IR, and graphics issues, where switching from one picture to another would cause both pictures to "overlap" and start flickering together. After constant frustration Apple pulled through with their amazing customer service and upgraded me to the top of the line Retina model, at no additional cost. again, this MBPr (i am typing this from it) also came with an LG screen with IR, and was also swapped to the samsung screen. I am now experiencing the same graphics issues as the last retina!! so i am posting to see if anyone else is experiencing the same thing, or if you guys can suggest any possibilites of what it could be, and what course of action i should take, as this is the second time. here is the link to the issue, recorded from my phone: http://s751.photobucket.com/albums/...14-B4B9-7246A1CC1722-338-0000000F5D432889.mp4 <-- this is on the current machine this next link is from my old machine, showing the exact same problem (posting for comparison): http://s751.photobucket.com/albums/xx151/STiTcHeDLiNk-/?action=view¤t=002.mp4 it seems to be happening with Flash based pictures, if that raises any suggestions.
