I did a git bisect, and it reported this:

    wined3d: Fix a few small bugs in WineD3D_ChoosePixelFormat.

The culprit is the middle hunk, i.e. this:

-    } else {
+    } else if(!iPixelFormat) {

The game is not requesting an automatic depth/stencil buffer, so
WineD3D_ChoosePixelFormat doesn't give it one.  However, this bug allows it to
call ChoosePixelFormat even though a valid one was already found.  It finds the
exact same pixel format, but apparently somehow with a depth buffer.
