小程序地图 标记大量标记点（50个以上）后地图会出现闪烁，直到标记点标记完成闪烁才停止

[图片][图片] 刚开始是一条绿色的线 想要匀速走过的轨迹线变成红色 但是轨迹线动态加载时一直在闪烁 js // 全屏地图路线图并动画移动 var ii = 0 var timer = '' // 坐标集合 let points = [{     longitude: 106.5538,     latitude: 29.50401,   },   {     longitude: 106.553907,     latitude: 29.499472,   },   {     longitude: 106.556354,     latitude: 29.487089,   },   {     longitude: 106.555667,     latitude: 29.485053,   },   {     longitude: 106.553285,     latitude: 29.476311,   },   {     longitude: 106.550131,     latitude: 29.473864,   },   {     longitude: 106.540174,     latitude: 29.468932,   },   {     longitude: 106.536183,     latitude: 29.469941,   },   {     longitude: 106.531312,     latitude: 29.469212,   },   {     longitude: 106.526527,     latitude: 29.471043,   },   {     longitude: 106.524317,     latitude: 29.47207,   },   {     longitude: 106.524253,     latitude: 29.471939,   }, // 轨迹点 . . . ]; Page({   data: {     markers: [], // 标记点集合     polyline: [], // 坐标点集合     satellite: false, // 是否开启卫星图     i: 0   },   onReady: function () {     this.mapCtx = wx.createMapContext('map'); // 创建 map 上下文 MapContext 对象   },   start() {     let that = this;     clearInterval(timer)     ii = 0     this.setData({       polyline: [{         points: points,         color: "#14C556",         width: 5       }],       // markers:markers,       longitude: 106.587891,       latitude: 29.544862,     })     timer = setInterval(() => {       ii = ++ii       if (ii == points.length - 1) clearInterval(timer)       that.translateMarker()     }, 500);   },   onLoad: function () {     let that = this;     this.start()   },   // 平移marker，带动画   translateMarker: function (markers) {     let that = this;     var passedpoint = [];     if (ii > 0) {       for (var pointsindex = 0; pointsindex <= ii; pointsindex++) {         passedpoint.push(points[pointsindex]);       }       let {         polyline       } = that.data       polyline.push({         points: passedpoint,         color: "#FF0000DD",         width: 3,         arrowLine: true       });       that.setData({         polyline       })     }   }, }) wxml <button bindtap="start">开始</button> <view class="container">   <map id="map" longitude="{{longitude}}" latitude="{{latitude}}" scale="12" markers="{{markers}}" polyline="{{polyline}}" enable-satellite="{{satellite}}" show-location style="width: 100%; height: 100vh;"></map>

移动地图 观看西安地区的marker

安卓机器都onCompassChange罗盘咋不管动不动一直返回数据，罗盘就不停的摇摆；ios都不存在这问题。
