SharpDX Viewport3DX transparent background not working

See original GitHub issue

Does sharpdx viewport3dx support transparent background? According to #579 and #867, setting backgroundcolor to #00000000 will make background transparent. But it is not working to me. Did I missed anything?

            <hx:Viewport3DX x:Name="view1"
                        Grid.Row="0"
                        Margin="0,20,0,0"
                        Background="#00000000"
                        BackgroundColor="#00000000"
                        Camera="{Binding Camera}"
                        CoordinateSystemLabelForeground="#434343"
                        EnableDesignModeRendering="True"
                        EnableSwapChainRendering="True"
                        FXAALevel="Ultra"
                        IsZoomEnabled="True"
                        MSAA="Maximum"
                        ShowCameraInfo="True"
                        ShowCameraTarget="True"
                        ShowCoordinateSystem="True"
                        ShowFrameDetails="True"
                        ShowFrameRate="True"
                        ShowViewCube="True"
                        TextBrush="Black"
                        UseDefaultGestures="False">
               </hx:Viewport3DX>

Setting backgroundcolor to #00000000 result in a black background. tim 20180730172308

Hello, This seems to work:

    <Grid Background="Green">
        <hx:Viewport3DX Background="#00000000" BackgroundColor="#00000000"
                        FXAALevel="Ultra" MSAA="Maximum"
                        EnableSwapChainRendering="False">
        </hx:Viewport3DX>
    </Grid>

The background becomes green: capture
