The screen color of my 2011 17" Macbook Pro changes to blue-ish every time the discrete graphics card is used! That started to happen only after I upgraded to OS Mountain Lion!


Whenever I open any app that use Discrete graphics card by default, the screen becomes blue and looks terrible.. Applications include, VLC, Chrome (20.0) and I guess quite a few others!


So now efectively my Macbook Pro has just one usable video-card - the buit in one, because the discrete card (AMD Radeon HD 6750M) is not usable!


Here's some other forums set up about this problem, so it's not just me:


***..!? Apple, please fix this ASAP!!!

MacBook Pro (17-inch Early 2011), OS X Mountain Lion
