I believe that's the Mica effect failing which is out of my control - the second screenshot (which I believe is the correct one) looks right, but I can see the white background of the window in the titlebar area of the first screenshot which is how I know. There have been other issues with Mica (https://github.com/AvaloniaUI/Avalonia/issues/6465) You can try adding an app.manifest file I think it is and see if that helps (see that linked issue in the Avalonia repo).

Closing as this issue does not appear to be directly related to FluentAvalonia
