Bug ID: 56752
           Summary: WoW Cata Classic 4.0 has grey artifacts flickering
                    through
           Product: Wine
           Version: 9.9
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown

Whenever i walk around the game, i have some grey polygons obstructing the view
every other step. Since the path in front of me and behind me has no major
obstacles, this seems to be a rendering issue.

I have yet to get a screenshot before it disappears again but i attached a
logfile.
