Game view does not resize correctly when window is maximised during loading

During loading a map in (non-maximised, normally launched) windowed mode, when I proceed to maximise window, the view stays the size of the original window. Does not happen after loading the map completes. Playing game/ pausing/ unpausing does not affect the position or size, the map must be exited before the view enlarges to match the window. Only happens on first map load after client launch. Subsequent loading of maps does not have the same issue it seems.
