Just did that with my laptop when he was in the launch pad and extremely quickly swiping through the Apps. Didn't have anywhere near that same issue he was having. I'm REALLY thinking that if you are experiencing these results, you might want to go to Apple and get a replacement.
To be clear, I see
some ghosting, in the same way that I see
some ghosting on my
LG UW Monitor. And to be fair to my LG UW, I don't have it at the fastest settings, but I know the panel, even not at its fastest settings, is still quite quick.
I really, really think this may be a defect and if you have this issue, contact Apple about it. I've been hearing more and more from both sides saying some have it and others don't.
EDIT: MORE NEWS. This might actually have to do with the brightness. If I am under 50% brightness, I notice ghosting a bit more, but its still not as bad as this video. When Im at max brightness, it's gone, effectively. That is to say, it's extremely hard for me to tell if there is ghosting or not at max brightness. At lower brightness (50% and below), I notice it more, I think.
