居中标题与所有其他右对齐标题不相配。相反,你可以使用https://topanswers.xyz/tex?q=1041增加部分页面的宽度,以便可以容纳所有标题:
\documentclass{beamer}
\usetheme{moloch}% modern fork of the metropolis theme
\makeatletter
\setbeamertemplate{section page}{
\centering
\begin{minipage}{\linewidth}
\raggedright
\usebeamercolor[fg]{section title}
\usebeamerfont{section title}
\insertsectionhead\\[-1ex]
\usebeamertemplate*{progress bar in section page}
\par
\ifx\insertsubsectionhead\@empty\else%
\usebeamercolor[fg]{subsection title}%
\usebeamerfont{subsection title}%
\insertsubsectionhead
\fi
\end{minipage}
\par
\vspace{\baselineskip}
}
\makeatother
