I can confirm this.
However what would the best way to debug the cause here?
As not everyone is experiencing this, it would be good to know wine/kernel/libraries versions and your distribution. Maybe we can get a correlation.
Ubuntu 12.04 x64 with kernel 3.8.0-36-generic and wine 1.7.12 from wine-ppa LoL with texture patch
