Hi, I've thought over this: If you want to connect the IWineD3DTexture and IWineD3DSurface refcounts only, then there's no problem for me. If you want to connect the Texture's and Surface's Parents refcount, then you have do the same for the rendertargets and the swapchain(I guess that Windows does that too), and I can use that connection to manage complex ddraw surfaces.
