I have a new NVidia GTX 180 (latest drivers) which is one of the latest high end releases in the GPU market. The problem is I'm experiencing the following issues in the composition(viewport) windows in After Effects and Premier Pro.
Basically parts of the view become cropped out. If I scroll in/out parts of the footage become visible. The only way to see a comp fully is to zoom out incredibly far. Also sometimes the UI seems to be effected moving down the screen.
I should add that I work in After effects professionally, I have tried simple solutions like changing the view quality, clearing caches, preferences, etc.
I haven't received any feedback on Adobe's forums.
