Wrong slide size with beamer, pstricks and Texlive

Question

This is a followup of my question here and uses the same setup.

MWE (test.tex):

\documentclass[dvips]{beamer}

\usepackage{pstricks}
\psset{unit=1mm}

\begin{document}

\begin{frame}\frametitle{Test}
line 1

line 2

\begin{figure}[h]
\begin{center}
\pspicture(0,0)(60,60)
\psframe(0,0)(60,60)
\endpspicture
\end{center}
\caption{Figure}
\end{figure}

line 3

\end{frame}
\end{document}

Workflow:

latex test
dvips -P pdf test
ps2pdf test.ps

Running this with Tex Live 2018 gives a wrong slide size. The problem seems to be in running dvips. Under Tex Live, the header in the postscript file is

%!PS-Adobe-2.0

Running dvips under MiKTeX gives the correct slide size:

Has anyone else noticed this problem and is there a fix?

Thanks.
