Summary0002594: Complex OpacityMask with transparency provides different results in WPF and Noesis 3.2.0
Description

Complex OpacityMasks with transparency can provide different results in WPF and Noesis 3.2.0. The problem can cause flickering when Opacity is animated. The issue wasn't noticed in version 3.1.6.

Steps To Reproduce

<Grid Background="Black">
<Grid>
<Grid.OpacityMask>
<LinearGradientBrush StartPoint="0,0.5" EndPoint="1,0.5">
<GradientStop Color="Transparent" Offset="0" />
<GradientStop Color="Black" Offset="0.5" />
<GradientStop Color="Transparent" Offset="1" />
</LinearGradientBrush>
</Grid.OpacityMask>

                            <Grid>
                                            <Grid.OpacityMask>
                                                            <LinearGradientBrush StartPoint="0.5,0" EndPoint="0.5,1">
                                                                            <GradientStop Color="Black" Offset="0" />
                                                                            <GradientStop Color="Transparent" Offset="1" />
                                                            </LinearGradientBrush>
                                            </Grid.OpacityMask>
                                            <Grid Background="Red" />
                            </Grid>
            </Grid>

</Grid>
