Summary: Hegemony Gold rendering artifact: border overlay only
                    shows in upper left corner of screen
           Product: Wine
           Version: 1.3.11
          Platform: x86
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: -unknown

installs and starts fine.

In the very first screen once the
game tutorial is underway (when it says "Pan the camera with..."
or "Zoom and rotate with ...",)
you can see a rotating leapard-spotted band surrounding the castle
(presumably showing the border of the region of influence of
the castle?).

On Windows, this band isn't confined to a region of the screen,
but in Wine, it is confined to the left half and upper third
of the screen, regardless of resolution or whether you've
selected fullscreen or windowed mode in the game.

This is on an Nvidia gt 240 with driver 260.19.06.
I also checked with wine-1.1.38, same problem.
