@aptgetmoo: The higher clock speed could be the reason for why the fire helps, but my assumption was that by drawing the fire I force the X-server(?) to continuously refresh the screen. To be honest, I don't know much about the internals, so be free to correct me :). By doing this, _all_ screen refresh problems disappear, so you could give it a try when it occurs again with oo or adobe.
