--- Comment #10 from genstorm andreas.sturmlechner@gmail.com 2012-02-11 18:30:12 CST --- I have identified the problem now as a regression from 1.3.14 to 1.3.15.
Taking a look at http://www.winehq.org/announce/1.3.15 there's... Reflection support in shader compiler ...introduced in that version. Could that be the cause?
