I attached an image of the issue of the screen. Before I downloaded the latest apple software update (to OSX 10.6.8) to prepare for the Lion update, it was fine and loaded without these bands. Now that I have updated, I have been getting these bands. I understand that with my MBP being pretty old, circa 08, it should be expected. Is it something that the graphics card doesn't like from the update or is my LCD screen going south? Any tips to fix it?
