--- Comment #2 from Stefan Dösinger stefandoesinger@gmx.at 2009-01-17 07:07:22 --- Judging from the screenshot and the workaround I think I have a fix for this problem.
Currently my wine tree has another branch checked out, but I'll send that fix within the next days. It is a set of patches that fixes how the fog source is selected, so it is slightly bigger than this code.
