Bug ID: 40318
           Summary: Star Wars Galactic Battlegrounds Saga - video glitchy
           Product: WineHQ Apps Database
           Version: unspecified
          Hardware: x86
                OS: Mac OS X
            Status: UNCONFIRMED
          Severity: major
          Priority: P2
         Component: appdb-unknown
          Assignee: [e-mail]
          Reporter: [e-mail]

I followed the process to install Wine HQ as spelled out on the FAQ, including
installing XQuartz, XCode, and MacPorts, and having MacPorts build Wine in the
Terminal. Then I downloaded Voobly and the Star Wars Galactic Battlegrounds
game found on GOG:
https://www.gog.com/game/star_wars_galactic_battlegrounds_saga

I installed both using Wine. Voobly works perfectly, but SWGB runs with normal
looking cutscenes but when it gets to the main menu the video flickers and
glitches so that it is unusable. I did some research and tried to remedy this
by opening up winecfg and setting it to emulate a virtual desktop, but it
seemed to have no effect.

If there is more information that will help troubleshoot this bug, let me know
where I should go to pull it. I'm still new to Wine and not sure what the most
relevant info is.
