Dual monitor App invisible

[ErikSom]

When running my window with the following settings:

    let main_window = WindowDesc::new(build_ui())
        .title("Keyboard Event Viewer")
        .transparent(true)
        .show_titlebar(false)
        .window_size((500.0, 160.0));

It will not show up on a dual monitor on MacOS 14.1.2. It will simply be invisible.

The culprit is .show_titlebar(false) when I comment it out the app will show.
