This will also happen when filling paths if AA is forced off, but I don't think that ever happens. See bug 66821 and bug 70471 for more info. Currently this has only caused a couple of minor bugs, one of which can be fixed in a different but inferior way. If drawConvexPolygon is used more or filling paths is used without AA, this might cause future pain.
