--- Comment #4 from Xavier Vachon xvachon@gmail.com 2013-09-18 20:33:58 CDT --- This is still a bug in wine 1.7.2. The bug happens occasionally and randomly : sometimes the polygons will appear properly and other times they appear like the screenshot I uploaded. The log for both good and bad cases is identical, so it's hard to tell what causes this bug.
