HarmonyOS 鸿蒙Next Canvas绘制，重绘时间很短（低于16ms），但是视觉上很卡

@Component
export struct CanvasView {
  private settings: RenderingContextSettings = new RenderingContextSettings(true)
  private renderContext: CanvasRenderingContext2D = new CanvasRenderingContext2D(this.settings)
  @StorageLink('validateCanvas') @Watch('redraw') private isValidate: boolean = true;

  redraw() {
    this.renderContext.reset();
    let t1 =
      Date.now();
    // 绘制逻辑 
    let t2 = Date.now();
    logger.debug(`canvas 绘制时间=${(t2 - t1)}ms`);
  }

  build() {
    Stack() {
      Canvas(this.renderContext)
        .expandSafeArea([SafeAreaType.SYSTEM], [SafeAreaEdge.TOP, SafeAreaEdge.BOTTOM])
        .width('100%')
        .height('100%')
        .backgroundColor(Color.Red)
        .transform(this.matrix)
        .backgroundColor(Color.White)
        .padding(this.calcPadding(this.isValidate))
        .onReady(() => {
          logger.debug("绘制流程 Canvas onReady");
          this.gestureAttacher.init();
          this.redraw();
        })
    }
  }
}

  当我打开屏幕录制时，绘制非常流畅，关闭屏幕录制后很卡
