I got the same Firebug warning when using polylines. Lawrence's
solution for polygons works for polylines too:
BEFORE
mypolyline = new google.maps.Polyline({
strokeWeight: 2,
strokeColor:"#0000ff",
strokeOpacity:0.5
});
mypolyline.setMap(map);
mypolyline.setPath(new google.maps.MVCArray([path]));
AFTER
mypolyline = new google.maps.Polyline({
strokeWeight: 2,
strokeColor:"#0000ff",
strokeOpacity:0.5,
fillColor: "#ffffff",
fillOpacity: 0.01
});
mypolyline.setMap(map);
mypolyline.setPath(new google.maps.MVCArray([path]));
