没看出来，可能只有一帧，不太好识别。 目前不仅是Xcode View Hierarchy存在此问题，lookin等也会，比较奇怪。 |

复现步骤：
① 运行iOS FSPlayerDemo
② 在主页使用Xcode View Hierarchy调试工具，如下图所示：
③ 关闭Xcode View Hierarchy，进入FSPlayer播放页面即可复现，此时画面大概率黑屏或者卡顿，在App运行期间内都会这样，除非重启App
④
[commandBuffer presentDrawable:drawable atTime:currentAttach.presentationTime]更换为[commandBuffer presentDrawable:drawable];能解决此问题，但尚未研究原因Tips：真机和模拟器均可以复现，但建议使用真机调试
