Uno Platform App on Linux Image not Showing

I am trying to get an Uno project running on a Raspberry Pi. I can get the basic project running but there are issues:

1. Use VS 2019 Uno Extension to create a cross-platform application.
2. Add an Image to the MainPage.xaml
3. Build
4. Publish Project.Skia.Gtk project to a folder on Pi
5. Run Project.Skia.Gtk from that folder.

MainPage comes up and text objects on the page are rendered. However, Image objects are not rendered.

In the Linux command window there is an error:

Windows.Ui.Composition.CompositionObject[0]
The member void CompositionObject.Dispose() is not implemeted in Uno.

Everything looks right on the UWP project.
