无法打开两个都在 tkinter 中显示视频的画布

如何解决无法打开两个都在 tkinter 中显示视频的画布

我正在处理一个项目，在该项目中我显示来自线程队列的视频源（它只是从实时网络摄像头读取和排队帧），使用 opencv 查看图像，应用跟踪，并生成阈值图像作为好。主视频源获取图像，转换为 PIL 图像并将其放在主画布上。获取图像的主菜单生成图像和阈值掩码，并将它们放在类变量中。当您打开遮罩菜单时，它只是抓取带有遮罩的变量，将其转换为 PIL 图像并应显示它。两个画布应该能够同时运行。但是在我的 PC（这是一个标准的 lenovo ideapad）上，不能同时显示，只能显示一个，但我的朋友（使用高端游戏电脑）可以同时打开两个。有没有原因，只是我的电脑不够强大？或者有没有办法让两者都运行？

这是代码，编辑以突出显示主要关注的代码：

root = Tk()

root.mainloop()

如果有人能帮忙那就太好了，谢谢。
