Offline Map and Ghosting effect of billboard item

I am using the offline map feature of Cesium and experiencing an issue with billboard icons in the 2D map view. The icons seem to ghost as you pan across the map. I have replicated this with the SandCastle demo, code is below. Is there a setting I am missing on this?

var viewer = new Cesium.Viewer('cesiumContainer', {
    sceneMode : Cesium.SceneMode.SCENE2D,
    imageryProvider : Cesium.createTileMapServiceImageryProvider({
        url : Cesium.buildModuleUrl('Assets/Textures/NaturalEarthII')
    baseLayerPicker : false,
    geocoder : false

            id: 1,
            name: 'Test',
            position: new Cesium.Cartesian3.fromDegrees(40.923664, -98.343286, 500),
            label: new Cesium.LabelGraphics({
              text : 'Test',
              font : '14pt sans-serif',
              scale: 0.75,
              horizontalOrigin: Cesium.HorizontalOrigin.CENTER,
              verticalOrigin: Cesium.VerticalOrigin.TOP,
              heightReference : Cesium.HeightReference.CLAMP_TO_GROUND,
              fillColor : Cesium.Color.BLACK,
              showBackground : true,
              backgroundColor : Cesium.Color.GHOSTWHITE,
              backgroundPadding : new Cesium.Cartesian2(8, 4),
              disableDepthTestDistance : Number.POSITIVE_INFINITY
            billboard: {
              image : 'data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAACAAAAAgCAYAAABzenr0AAAAbElEQVR42mNgGAUDDf7///9vIDG9HfAXiB8A8R9sDlgAxPlUwFvxOKAEGurBUMegOKCQSlE6FYflX4GYC0ndw4EIgSKo5UHYQmDA08DA5IJRMFoQjRZEowXRaEE0WhCNFkSjBdFoQTQKRjwAABfDLXwNNSZEAAAAAElFTkSuQmCC' , //iconUrl, // default: undefined
              show : true, // default
              horizontalOrigin : Cesium.HorizontalOrigin.CENTER, // default
              verticalOrigin : Cesium.VerticalOrigin.BOTTOM, // default: CENTER
              scale : 0.75, // default: 1.0
              color : Cesium.Color.WHITE, // default: WHITE
              alignedAxis : Cesium.Cartesian3.ZERO, // default
              eyeOffset : Cesium.Cartesian3.ZERO, //new Cesium.Cartesian2(0, -50),
              pixelOffset : Cesium.Cartesian2.ZERO, //new Cesium.Cartesian3(0.0, 0.0, 0.0),
              height: 32,
              width: 32,
              distanceDisplayCondition : Cesium.DistanceDisplayCondition(10.0, 20.0),
              heightReference: Cesium.HeightReference.CLAMP_TO_GROUND,
            box: new Cesium.BoxGraphics({
               dimensions: new Cesium.Cartesian3(0, 0, 0),
               fill: false,
               outline: true,
               outlineColor: Cesium.Color.WHITE,
               outlineWidth: 1.0

This appears to be happening in Chrome: Version 60.0.3112.113 (Official Build) (64-bit) and does not replicate in FireFox.


By offline map feature, do you mean following the Offline Guide? If so, the usage of the imagery provider should not be affecting the behavior of billboards.

I’m having trouble replicating the error in either Chrome or Firefox, can you provide an image of what you’re seeing, or preferably show it with a simple Sandcastle Example?
