我在geo地图中使用了effectScatter后，cpu占用率激增

Expected Behavior

能够降低cpu占用

占用率如下（火狐浏览器）：

{ name: '涟漪图', type: 'effectScatter', showEffectOn: 'render', coordinateSystem: 'geo', rippleEffect: { period: 6, scale: 6, brushType: 'fill' // 动画中波纹的最大缩放比例。stroke fill }, animation: false, // data: seriesData.fluxSeriesData, data: [ { "symbolSize": 12, "itemStyle": { "color": "rgba(250,58,71,0.6)" }, "value": [ "116.403039", "39.914909" ] } ], z: 1 }
