This is what the OffscreenRenderMethod option is for. If it's set to 
backbuffer, wined3d needs to use the backbuffer as well as it can. If you 
need to use pbuffers, set it to pbuffer (which I believe is the default?). Or 
if the card supports it, use fbo, which is more flexible (and needed for some 
of D3D9's capabilities, IIRC).
