# Beamer: margins in metropolis theme when combined with infolines

I am using the metropolis theme and I want to combine it with

\useoutertheme{infolines}


It works nicely except of the following: the margins are affected in a way that I don't like. So my question is: can I combine infolines with metropolis but still keep the original margins?

Below is a minimal working example. To make sense, one needs to compare the compilations with the line \useoutertheme{infolines} commented and uncommented.

\documentclass[t]{beamer}
\usetheme{metropolis}

%\useoutertheme{infolines}
\usepackage{lipsum}

\title[Title]{A descriptive Title}
\author[F]{First Author, Second Author, Third Author}
\institute[U]{University of}

\begin{document}
\maketitle

\section{Introduction}

\begin{frame}
\lipsum[3]
\end{frame}

\end{document}


The infolines theme sets margins to 1em. You can restore the default margins via:
\setbeamersize{text margin left=1cm,text margin right=1cm}
