Bug happens in any Wine version from 1.5.0 and up, while using proprietary FGLRX driver
I'm using nVidia blob, and it only started happening with the specified regression commit (somewhere between 1.5.27 and 1.5.28)
In early Diablo 3 versions this bug didnt occurs, prior the patch 1.0.2 the bug started to happen.
Unfortunately one can only test with the latest Diablo 3 version, due to the way the game is designed.
