I am using leaflet to create a set of swipable layers. Mapbox has an example of this: https://www.mapbox.com/mapbox.js/example/v1.0.0/swipe-layers/ My issue is that when a layer is getting clipped UTFGrid does not respect it. So it still gives the UTFGrid data for the last added layer. When hovering the other layer. Hopefully this make sense.
