Um, the demotest version doesn't use delta stuff -- so space updates should
be reflected immediately.

More likely, what you're seeing is that a new vobscene is not being generated
but the old one is not updated properly:

For speed, we want to update the old vobscene's coordinate systems and
redraw while dragging; otherwise, frame rate is just too low.
