该background包导致 tikz 错误verbatim
我在 begin/end 中有几行文本verbatim，通常这只会在需要的地方分页，但是，当我使用该background包时，它会产生一些tikz Error：
Package tikz Error: Sorry, some package has redefined the meaning of the matht cause unrecoverable errors. \end{verbatim}
我已经能够在没有该包的情况下生活，但我很好奇为什么会发生错误，有没有解决方法，或者这是软件包中的一个错误？这种情况仅当逐字逐句超过一页时才会发生，就像在 MWE 中一样，如果我减少 lipsum 以使其不会分页，那么错误就会消失。
平均能量损失
为了使换行准确无误，我在需要的地方添加了一些虚句。
\documentclass[11pt,a4paper]{article}
\usepackage{background} % Letting me add background overlays.
\usepackage{lipsum}
\begin{document}
\lipsum[1-4] % Change this to \lipsum[1-3] and it goes away.
