I have an imac 20" early 2008 with Mainstage 2.2.2 (420.4) . When some days ago i've upgraded to Mountain Lion i have casual graphic problems in Mainstage , mostly in the workspace ,i have various patters of funny colors , the buttons are barely recognizable ,and when i switch to other programs (i.e Safari) there are also here some little areas with wrong colour points . 

When i try to enter Perform mode i receive this error :

Error entering full screen 

This could be due to lack of video memory. If you have multiple monitors, please try turning one off or reducing its resolution. You can also try connecting one of the two monitors to a secondary graphics card.

Needless to say i have only integrated monitor.

The imac has 4 GB of memory .

tried to throw away and reinstall Mainstage (buyed from Mac App Store) but have no luck .

Anyone can help me ?
