[Bug 10696] New: Direct3D mode in Age of Wonders 2 demo is unusably slow and glitchy

http://bugs.winehq.org/show_bug.cgi?id=10696

Summary: Direct3D mode in Age of Wonders 2 demo is unusably slow
                    and glitchy
           Product: Wine
           Version: 0.9.50.
          Platform: Other
        OS/Version: other
            Status: UNCONFIRMED
          Severity: enhancement
          Priority: P2
         Component: wine-directx-d3d
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

(Demo available at http://www.triumphstudios.com/ageofwonders2/files.html; it
installs quite painlessly.)

Note that Direct3D mode is the default for this game, but can be turned off
through the included configuration app aow2Setup.exe.  However, when Direct3D
mode is not enabled, some graphical effects are disabled.

Multiple issues with Direct3D mode in Age of Wonders 2 demo; I'm not really
sure how related these are, but I'll put them together, I guess, since I'm not
sure separate bugs would be useful without any real idea of what is causing
these effects:

1. In-game repainting speed is unusably slow. (To get in-game quickly, press
the "Tutorial" button.)

2. There are graphical glitches in-game: for one very obvious example, use the
scroll wheel to change the zoom level, and all the UI on the bottom gets
painted over.

3. The "buy now" screen (accessible by clicking "Quit" on the main menu)
flickers severely.

I'm using Wine 0.9.50 on Ubuntu 7.10; I have an Intel Core Duo and and
ATI　Mobility X1400, and I'm using the version of fglrx that comes with
Ubuntu.
