      (seems to be reproduced as well on Mer X86 inside virtualbox)

      QtWayland demo compositors are lagging when updating the view (drawing the application inside the compositor).

      For example, with a button, when the button is pressed, it is displayed as pressed, but when released, the view is not updated, it is still displayed as pressed. While pressing another button, the first button that was displayed as pressed, is then drawn, and is no longer pressed.
