Writing \lineskiplimit=-\maxdimen produces blank space instead of equation when using the split equation from amsmath

Question

I'm writing an mathematical article and find it not aestetically pleasing that writing math symbols inside plain text often produces uneven line spacing. I found a solution to this by writing \lineskiplimit=-\maxdimen in the preamble and in the anser by ClintEastwood here. This has been working great until today when I wrote an equation using the equation and split enviroment from amsmath and it just produces a blank space.

Is there an easy fix to this or should I try solve the linespacing problem by other means?

I'm using Overleaf but also tried the following code in MikTeX version 2.9.

\documentclass{article}

\usepackage{amsmath}
\lineskiplimit=-\maxdimen %this gives us even line spacing, 


\begin {document} 

\textbf{Verify that $A \cap (E+ \beta )^c = (A- \beta  \cap E^c ) + \beta$}

\begin{equation*}
    \begin{split}
    \mu ^*(A \cap (E+ \beta)) + \mu ^*(A \cap (E+ \beta)^c )  &= \\
    &= \mu ^* ((A- \beta \cap E) + \beta) + \mu ^*((A- \beta  \cap E^c ) + \beta) \\
    &= \mu ^* ((A- \beta \cap E)) + \mu ^*((A- \beta  \cap E^c ))  = \mu ^*(A)
    \end{split}
\end{equation*}


\end {document} 

Much grateful for any help provided!

Answer 1

In order to adjust the spacing at the top of the display, amsmath does (amongst other things)

                \vskip-\lineskiplimit

so with your setting that is a vertical skip of the maximum possible dimension in TeX, which not surprisingly pushes the display off the page.

Setting \lineskiplimit this way really can not be recommended as a global default (although it is a useful technique in controlled situations).

But if you really want to do this then (a) set \normallineskiplimit to match and also (b) adjust the mathstrut calculation not to use the negative value.

\documentclass{article}

\usepackage{amsmath}
\lineskiplimit=-\maxdimen %this gives us even line spacing, 
\normallineskiplimit\lineskiplimit

\makeatletter
\def\reset@strutbox@{%
  \global\setbox\strutbox@\hbox{%
\normallineskiplimit=0pt
    \lower.5\normallineskiplimit
       \vbox{\kern-\normallineskiplimit\copy\strutbox}}}
\makeatother

\begin {document} 

\textbf{Verify that $A \cap (E+ \beta )^c = (A- \beta  \cap E^c ) + \beta$}
\begin{equation*}
    \begin{split}
    \mu ^*(A \cap (E+ \beta)) + \mu ^*(A \cap (E+ \beta)^c )  &= \\
    &= \mu ^* ((A- \beta \cap E) + \beta) + \mu ^*((A- \beta  \cap E^c ) + \beta) \\
    &= \mu ^* ((A- \beta \cap E)) + \mu ^*((A- \beta  \cap E^c ))  = \mu ^*(A)
    \end{split}
\end{equation*}


\end {document} 

This makes a visible output (although naturally with poor vertical spacing)
