I own the newest model of the 15" non-retina MBP. Recently, I've noticed a strange occurrence. Whenever I open a game or watch a netflix video the computer screen immediately flashes to a brighter color and holds that new, brighter color scheme until I quit out of the game or video. Perhaps it has been doing this all along but I think it just started happening. My only conclusion is that this is what happens when the graphics cards switch back and forth. What do you all think?
