# Why does pgfpages not allow plain text in a beamer column environment?

Using XeLatex and beamer class, I want to make a presentation with notes. The pgfpages package does this nicely. But when I make a column environment AND want the notes produced, then text will not appear although itemize items will. This seems weird!

MWE:

\documentclass[11pt]{beamer}
% Beamer Setup
\usetheme[progressbar=frametitle]{metropolis}

%%%%%%% notes
\usepackage{pgfpages}
%\setbeameroption{hide notes} % Only slides
%\setbeameroption{show only notes} % Only notes
\setbeameroption{show notes on second screen=left} % Both

\usetheme{default}
\begin{document}

\begin{frame}
testing
\end{frame}

\begin{frame}
\begin{columns}
\begin{column}{.5\linewidth}
stuff
\end{column}
\begin{column}{.5\linewidth}
content...stuff here too
\end{column}
\end{columns}
\end{frame}

\begin{frame}
\begin{columns}
\begin{column}{.5\linewidth}
\begin{itemize}
\item stuff here
\item and here
\end{itemize}
\end{column}
\begin{column}{.5\linewidth}
but stuff only appears here when you are not showing notes
\end{column}
\end{columns}
\end{frame}

\end{document}


What's going on here?
