Opencv4.5.1+Visual Studio2019 程序运行窗口异常

最近刚开始学opencv,在读取视频文件的时候出现了问题
程序的功能都正常实现了,但是运行窗口上多了一堆奇怪的东西,如图

代码

#include <opencv2/opencv.hpp>
#include <iostream>

using namespace cv;
using namespace std;

int main()
{
    

    VideoCapture video("D:/Downloads/rain.mp4");
    if (video.isOpened())
    {
        cout << "视频中图像的宽度为:" << video.get(CAP_PROP_FRAME_WIDTH) << endl;
        cout << "视频中图像的高度为:" << video.get(CAP_PROP_FRAME_HEIGHT) << endl;
        cout << "视频帧率为:" << video.get(CAP_PROP_FPS) << endl;
        cout << "视频总帧数为:" << video.get(CAP_PROP_FRAME_COUNT) << endl;

    }
    else
    {
        cout << "请输入正确的文件名称" << endl;
        return -1;
    }
    while(1)
    {
        Mat output;
        video >> output;
        if (output.empty())
        {
            break;
        }
        imshow("video", output);
        waitKey(1000 / video.get(CAP_PROP_FPS));
    }
    waitKey();
    destroyAllWindows();
    return 0;
}

应该是具体过程吧
