Lighter spot on macbook screen
So I have a black macbook and I still have warranty on it but today as I was editing some pictures in iPhoto, I noticed the bottom left has a "blotch" where the colours are lighter than everything else on the screen. The "blotch" is noticeable when you are looking at darker pictures. It used to be smaller but now its expanded. I've made an appointment with the genius bar to see if they can do anything about it, but I was wondering if any of you guys had any problems similar to mine.
