Hi all, since some time i get graphic issues, like in the screenshot. They disappear automatically or when i scroll down the website / application. The macbook is not too hot, about 50 degress celsius. Do you think the graphicard is crappy, and need to be replaced? If so, how long does it take, when i take the macbook to an offical apple store? It would be nice if someone know a simple fix for that! I wont live without my macbook ;-) I use LION 10.7.2. Thanks for your tipps!
