            change must not tear that down and rebuild it, so the activity handles them itself.
            Landscape only: gamescope is told one output size when it starts.

            Resizable, deliberately: a foldable opening or closing changes the window, and the
            compositor re-fits the picture with bars. Declared non-resizable, the system keeps a
            fixed-shape window instead and STRETCHES it onto the other panel - the app never sees a
            size change, so nothing it does can help.
