Changing displayskips glitches titleps

Question

I'm using titleps for my masters thesis. When I change the displayskips as per this answer the headings become offset. Without using rubber spacing the headings are only minimally offset. I would really appreciate some advice, please.

\documentclass{book}
\usepackage{blindtext}
\usepackage{etoolbox}

%%%%%%%%%SPACING%%%%%%%%%%%%%%%%%
\apptocmd\normalsize{
\setlength\abovedisplayskip{.5cm plus .1cm minus .1cm}
\setlength\belowdisplayskip{.5cm plus .1cm minus .1cm}
\setlength\abovedisplayshortskip{.1cm plus .1cm minus .1cm}
\setlength\belowdisplayshortskip{.5cm plus .1cm minus .1cm}}{}{}

%%%%%%%%%%%%%%PAGESTYLES%%%%%%%%%%%%%%%%%%%%
\usepackage[pagestyles]{titlesec}

\newpagestyle{main}[\small]{
\setheadrule{.3pt}
\sethead[Chapter \thechapter][][]
{}{}{\thesection \, \sectiontitle}
\setfoot[\thepage][][]
{}{}{\thepage}}
\pagestyle{main}

\begin{document} 
\Blindtext
\end{document}

I don't see the problem. Is it the widow at the top of the second page? — Bernard, Feb 02 '17 at 10:55

Your modification to the code for \normalsize is adding extra spaces in the output, one for each newline in the code. You need to comment out these end of lines using % characters as follows

\apptocmd\normalsize{%
\setlength\abovedisplayskip{.5cm plus .1cm minus .1cm}%
\setlength\belowdisplayskip{.5cm plus .1cm minus .1cm}%
\setlength\abovedisplayshortskip{.1cm plus .1cm minus .1cm}%
\setlength\belowdisplayshortskip{.5cm plus .1cm minus .1cm}}{}{}

See What is the use of percent signs (%) at the end of lines? for related discussion.
