Xamarin.Forms Editor resizing jitter in UWP project

infinityeternity 21

Why is there a jitter on Editor resizing on a new line?

<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             x:Class="JitterBugTest.MainPage">

    <StackLayout>
        <Editor AutoSize="TextChanges"/>
    </StackLayout>

</ContentPage>

Also the case when I try manually resize it inside OnTextChanged. But there is no such problem for a regular UWP project using corresponding TextBox class with AcceptsReturn="True".

How can I fix this?

I have tested with official code sample, but we could not reproduce this problem, could mind share minimal reproducible example?

There is nothing to share. This is a starter project from xamarin mobile template with the given code as a content page. I've recorded gifs for better demonstration.

Yep, I could reproduce this problem, and it looks a bug for Editor, please feel free post this problem within Xamarin Forms Issue Box here.
