AMD Radeon HD 6750M
Hello
my Macbook Pro 15 "2011 has a problem with the video board. When using 3D graphics, the screen changes color and when I pass the mouse pointer over the" dock "this starts to shake. When I switch from one desk to another one you will see a line in the middle of the screen that disappears after 1 second.
MacBook Pro, OS X Mountain Lion (10.8.2)
