Hi,


   I think it is some other problems. DX version of J3D
did set the clipper using the following code:

   LPDIRECTDRAWCLIPPER pcClipper;
    hr = pDDraw->CreateClipper(0, &pcClipper, NULL);
    if (FAILED(hr)) {
        error(CLIPPERFAIL, hr);
        return false;
    }
    pcClipper->SetHWnd(0, hwnd);
    primarySurface->SetClipper(pcClipper);
    pcClipper->Release();

Have you try runing those example come with
DirectX SDK to see if the artifact happen ?

Thanks.
