My 2011 MacBook Air is having some troubling problems. The first is that when I tried to load high resolution images, they will not render correctly, most asymptomatically the images will turn out more red until I zoom into them, at which point they look normal. At other times, they will not render correctly, at all! They will have lines of various sites I have browsed instead of the image(this is sometimes embarrassing ). Also when I move the display, sometimes a bar will appear vertically across a large part of the screen. I've attached an image. Does anyone else have a similar problem or know what part is failing? I have AppleCare, but I am in college, so being without my computer is going to impact my studies and grades.
