When a polygon is drawn on the map and the map is dragged, the position of the polygon relative to the GM V3 base changes.

function init() {
    var map = new OpenLayers.Map('map');
    var gsat = new OpenLayers.Layer.Google(
        "Google Satellite",
        {type: google.maps.MapTypeId.SATELLITE, numZoomLevels: 22}
    drawVctr = new OpenLayers.Layer.Vector("Editable Vector");
    map.addLayers([gsat, drawVctr]);

    // Google.v3 uses EPSG:900913 as projection, so we have to
    // transform our coordinates    
    var lng = "-71.118004"; 
    var lat =  "42.389118"; 
    map.setCenter(new OpenLayers.LonLat(lng, lat).transform(
        new OpenLayers.Projection("EPSG:4326"),
    ), 19);
    drawPlygn = new OpenLayers.Control.DrawFeature(
  • Don't want to mark this as a dupe since I'd like to actually see this issued fixed and there's lots of good info here. If this question is resolved then we can close the other as well. gis.stackexchange.com/questions/36774/… – Vadim Apr 6 '13 at 3:05

A similar issue has been reported and closed, marked with a comment that it cannot be fixed unless Google Maps fixes an issue on their end. I on the other hand, believe it is fixable by using MVCObject's bindTo. I'll start the conversation on the closed github issue.

  • This issue is across all browsers, and is due to a delay of Google Maps and OpenLayers staying in sync. – Andrew Ferk Apr 5 '13 at 16:33
