Found the reason! In Catalyst Control Center, there are 3 options for anti-aliasing: multisampling, adaptive multisampling and supersampling. The problem happens in adaptive mode, the other two are alright.

Works fine on the other laptop with Nvidia. Anyone else tried on a similar config?

The same issue appears in the editor. Normal FE works fine.

The game shows white area instead of 3d map. When I zoom out, I can see cloth map. The interface is visible. Windows 8 64-bit, AMD 6970m (laptop), latest non-beta Catalyst.
