Well, the result probably is correct, but does not describe the
visibility in your sense  :)

To track the effective visibility state connect a callback to the
visibility-notify-event signal. This gets invoked whenever the
visibility changes and you'll get a GdkVisibilityState, indicating if
your widget is fully visible, partially obscured or fully obscured.

Hope this helps,
