Seconded. The SVGALib driver is a scrolling driver, but the docs for
scroll_screen() are pretty clear:
"Allegro will handle any necessary vertical retrace synchronisation when
scrolling the screen, so you don't need to call vsync() before it. This means
that scroll_screen() has the same time delay effects as vsync()."
Peter, you're the specialist here, how comes that the driver doesn't seem to
wait for the vsync ?
