Code review comment for lp:~mzanetti/unity8/unified-stages

As far as I remember, ApplicationWindow.fullscreen had a single purpose left: ensure that a fullscreen application, when killed by the OutOfMemory daemon, retained its size instead of switching to a normal/restored size (ie, screen size minus the status bar). In phone mode particularly. That information came from qtmir's Application.fullscreen, which retained the state from its last surface.

But that property sure is (or was) tainting the API.
