我在笔记本电脑上安装了 Linux Mint 20（thinkpad x1 Yoga 第 4 代 | intel core i7 第 10 代），我通过更新管理器更新了需要更新的所有内容，但是当我打开 YouTube 上的视频甚至我的计算机上存在的视频时观看时，横向出现黑条（附视频）。也有一种情况是，我在浏览器中快速滚动浏览一篇文章，或者当我滚动日志文件时，这些行会被涂抹一会儿，然后返回到正常状态。
这是截图视频：https://drive.google.com/file/d/1I3GIrG6ZMq_vhhpFK_DepjYfKG64UcEm/view?usp=sharing
这是 inxi -Fxz 的输出：
