Matteo Bruni (@Mystral) commented about dlls/wined3d/context_gl.c:
current = gl_info->gl_ops.wgl.p_wglGetPixelFormat(dc); if (current == format) goto success;
- if (current && !private)
return FALSE;
I guess we could add a WARN("Using pixel format %u already set on DC %p.\n", current, dc); or something.
