--- Comment #1 from Karsten Elfenbein kelfe@gmx.de 2007-08-11 06:18:52 --- from debugging it seems that the format check seems to fails
dlls/wined3d/directx.c IWineD3DImpl_CheckDeviceType grabs DescribePixelFormat into nCfgs but in this special case nCfgs is empty
adding if (DisplayFormat==WINED3DFMT_X8R8G8B8) { WineD3D_ReleaseFakeGLContext(); return WINED3D_OK; }
works around this issue and the login screen appears as intended
