When using google map's control, the google map refreshes with new pre-cached tiles first, while the picture of the dynamic service remains while waiting for a new image. Thus, if the server renders slowly, it can cause an impression of a 'shift' but it's actually the previous extent's image...until the new image is served.</SPAN><BR /><BR /><SPAN>You can test out the effect here: </SPAN><A href="http://help.arcgis.com/en/webapi/javascript/gmaps/samples/maps/map_add.html">http://help.arcgis.com/en/webapi/javascript/gmaps/samples/maps/map_add.html</A><BR /><SPAN>Do not zoom or pan too fast first, to see that the dynamic map overlays correctly, then 'overload' the server by making faster changes to the map extent while observing the 'previous' image of the dynamic layer being shown until the new one is ready.</SPAN><BR /><BR /><SPAN>Hope this explains. Just my two cents.</SPAN><BR /><BR /><SPAN>Cheers,</SPAN><BR /><SPAN>Raymond</SPAN></BODY></HTML> Tue, 20 May 2014 07:38:36 GMT RaymondHuang 2014-05-20T07:38:36Z map shifted when overlay arcgis dynamic layer on google map using api 3.0? https://community.esri.com/t5/arcgis-enterprise-questions/map-shifted-when-overlay-arcgis-dynamic-layer-on/m-p/185605#M7395 <HTML><HEAD></HEAD><BODY><SPAN>Does any has similar issue on map shift when overlay dynamic layer on google map?
