This // happens in particular circumstances (Classic mode, Chrome using hardware // rendering, and the window on a secondary monitor) and when moving the mouse // over the window, Windows restores the GDI software surface underneath the // mouse, rather than the hardware surface we've painted. As a result, for // small or infrequently painting windows, we force back to the software // compositor to avoid this bug.
