--- Comment #4 from Dan Kegel dank@kegel.com 2013-07-05 12:02:58 CDT --- The fact that you're using wined3d on windows in no way prevents you from finding the git change that caused the regression.
If you aren't able to build wined3d for some other reason (like, you aren't a C developer and aren't comfortable building C libraries), that's another matter.
