Windows App SDK 1.4 TextBox text is shaky when resizing window

Question

I find that when I place a TextBox control inside a <RelatviePanel> and align its sides with the panel the text gets jumpy when I resize the height of the window. If I change the property TextWrapping to "NoWrap" then the problem goes away but I want the text to wrap and be able to resize the window without the text jumping up and down ...

<?xml version="1.0" encoding="utf-8"?>
<Window
    x:Class="LayoutTest.MainWindow"

    <RelativePanel>
        <TextBox
            Visibility="Visible"
            x:Name="directions"
            TextWrapping= "Wrap" 
            Background="White"
            Foreground="Black"
        
            RelativePanel.AlignRightWithPanel="True"
            RelativePanel.AlignLeftWithPanel="True"
            RelativePanel.AlignTopWithPanel="True"
            RelativePanel.AlignBottomWithPanel="True"

            >
        </TextBox>

    </RelativePanel>
    

</Window>

Hello @Brian Duffy,

I can reproduce but it could be by design. RelativePanel.Align*WithPanel and Wrap may cause some more calculation which causes the shaky. If I remove all RelativePanel.Align*WithPanel properties, then the problem also goes away.

You can still submit an issue at https://github.com/microsoft/WindowsAppSDK/issues.
