SL 5 out of browser - 1pixel white border?

Question

I have a SL 5 app set to run out of browser.
The OOB setting:

<WindowSettings Title="Thing" Height="497" Width="462" WindowStyle="BorderlessRoundCornersWindow" />  

Blend reports the width and height for the UserControl as 463, 500.
When the app runs out-of-browser, it appears there is a 1 pixel line of white along the left and top edges.
Some xaml:

       <Grid x:Name="LayoutRoot" Height="500" >
    <Border  BorderThickness="1" CornerRadius="6" Padding="2" Background="#FFF17A35">
        <Grid Background="Transparent">
            <Grid.RowDefinitions>
                <RowDefinition Height="Auto" />
                <RowDefinition Height="Auto"/>
                <RowDefinition Height="Auto" />
                <RowDefinition Height="Auto" />
                <RowDefinition Height="Auto" />
            </Grid.RowDefinitions>
            <StackPanel Orientation="Horizontal" HorizontalAlignment="Right" Margin="0,0,4,6">
                <HyperlinkButton
                    <!--blah blah -->
                </HyperlinkButton>
                <HyperlinkButton x:Name="hyperlinkCloseButton"
                    <!--blah blah -->
                </HyperlinkButton>
            </StackPanel>
            <StackPanel Orientation="Vertical" Grid.Row="2" HorizontalAlignment="Center" Margin="0,2,0,0">
                <StackPanel Orientation="Horizontal" HorizontalAlignment="Center">
                    <!--blah blah -->
                </StackPanel>
            </StackPanel>
            <ScrollViewer Width="400" Grid.Row="4" VerticalAlignment="Center" MaxHeight="76">
                <TextBlock x:Name="DbgOutput" 
              Text="{Binding DbgMsgTxt}"
               Width="396" TextWrapping="Wrap"/>
            </ScrollViewer>
        </Grid>
    </Border>
</Grid>

Any hints on where the whiteness is coming from?
