--- Comment #3 from Felipe Gustavo de Oliveira felipe.nemesis@gmail.com 2013-04-20 20:34:25 CDT --- Are you using setarch i386 -3 wine diablo3.exe to lunch the game?
When warden its active on server side playing the game without setarch in a x86_64 enviroment always brings gui corruption, low fps and gui elements stopping to response. Also Auction house stops to work.
Lunching the game with setarch i386 -3 fix the insue, however the performance decreases a little.

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.
