            Bug ID: 52684
           Summary: Command and Conquer Generals (and C&C Zero Hour) have
                    no ground textures
           Product: Wine
           Version: 7.3
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: directx-d3d
          Assignee: wine-bugs at winehq.org
          Reporter: bender647 at yahoo.com
   Regression SHA1: 1632b8e7a419ebf256c4a356a58d505ef918f2fe
      Distribution: Slackware

Introduced in wine-7.3 with commit 1632b8e7a419ebf256c4a356a58d505ef918f2fe,
the C&C Generals game engine does not draw ground textures.  The ground (or
water) area is black.  Reverting to wine-7.2, or applying this commit as a
reverse-patch on wine-7.4 will fix the issue.  The commit was found by
bisecting the git tree.

This symptom appears in older bug reports but the fixes there do not appear to
work now.

Tested on two platforms, but both were Intel i915 graphics.  If necessary, I
can get access to an Nvidia platform.

To reproduce:
1. A free demo is available for download to run the game:
https://www.moddb.com/downloads/start/111369
(https://www.moddb.com/games/cc-generals/downloads/command-conquer-generals-demo).
2. Install in 32-bit prefix.
3. Run with `wine start generals.exe -nologo` and the game engine will be seen
running behind the main menu.  The ground will be blank if the bug is present.
