This sounds like bug 1655804. It may require the same kind of fix: The toolkit needs to register its Mir event callback in the spec prior to window creation to support Unity8 behaviour.

As if launched in desktop mode. Comments: Leaving staged mode and going back into it again gets the application to resize correctly and fill the entire stage area. Going from desktop to staged mode while the desktop application is already running also works fine.
