I'm not sure if it's relevant for this particular change, but in the
Dreamcast backend, a call to updateScreen() is needed to update the
screen (this renders a new scene, and causes a page-flip).  If it is
not called, the previously rendered scene will simply be shown, and
nothing moves, including the cursor.

I think there was a problem with this in some engine (queen?) but it
was easily fixed by inserting a call to updateScreen() in the relevant
place.
