此代码与 QR（背景）产生了一些问题，如下所示：
在某些页面上，这没问题，但在其他一些页面上，则不然。
我发现如果我注释掉这些行
\makeatletter
\renewcommand\tableofcontents{
\@starttoc{toc}
}
\makeatother
我曾经修复过tableofcontents。然后它又正常工作了……
为什么？我该如何解决这个问题，但这个问题却一直没有显示Contents出来？

有人建议改用article类，但我在多次编译时遇到了同样的问题......
这可能是 MikTeX 发行版的一个错误吗？
如果我也发布日志会有帮助吗？
有人有任何线索吗？
