Thank you for the nice reproduction project. In this case, the issue is that the Window is not properly themed which is why when switching to Dark theme, the background and foreground of the text both become while. If you add Style="{StaticResource MaterialDesignWindow}" to your MainWindow you will see the problem is fixed.
