This may be normal and just me being nitpicky, but it's had me worried nonetheless. After about five minutes of use, when I activate Mission Control, I can see (thanks to the darker background) that my screen has some burn-ins. Most notably where the whites used to be located on the screen (most other colors don't burn in as much). You can just see the silhouettes, but if I use, say, Chrome for a lengthened period of time, and then go into Mission Control, I can actually read " Chrome" on the top left of the screen. Is this normal? Sure, it goes away after a while, but I can't help but feel I'm damaging the display, even if it's ever so slightly. I tried taking pictures so show how it gets after ten minutes of use, but those turned out all fuzzy, due to the screen also being a light source and what not. So, uhm, yeah. Anyone else having this? I shouldn't be worried, right? Thanks all!
