Renderproblem RichTextBox Windows Phone 8

问题

I'm implemented a RichTextBox in WindowsPhone 8. I fill this Box while runtime with Paragraphs, Runs, Images and HyperlinkButtons. The Problem that now appears is after some lines of content the RichTextBox is cut. I declared a red border that is also cut. Links and images are still displayed. Here is a Screenshot:

My XamlCode is simple:

<Grid x:Name="LayoutRoot" Background="Transparent">
    <ScrollViewer>
        <RichTextBox x:Name="ContentBox"  HorizontalAlignment="Stretch" VerticalAlignment="Top" BorderThickness="2" BorderBrush="Red" >
        </RichTextBox>
    </ScrollViewer>
</Grid>

Any idea what the problem is or is it a simulator bug?

Given that the fill-rate counter is at 2.4 my crystal ball tells me that you're hitting the 4096px limit of size for a single UI element. If that's the case you'll have to split up the RichTextBox content between several different controls.
