Seems like a wined3d bug, I think. dlls/wined3d/directx.c:wined3d_check_device_type() has a number of checks of the display and backbuffer format. For several of the checks, the comment says the restriction only applies for full-screen mode but the check doesn't take windowed vs. full-screen into account. The game is using windowed mode, but a supposedly full-screen-only check rejects the display/backbuffer format combination. In fact, that function has a check which specifically allows WINED3DFMT_UNKNOWN in windowed mode, but the subsequent logic makes it impossible for that to pass. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
