[pstricks] Differences in the output of \psdots TeX Live 2021 (win/linux)

Differences in the output of \psdots TeX Live 2021 (win/linux)


Hi all, I have a little dilemma with `\psdots` and I don`t know if it
can be solved from the `pstricks` side. I am using TeX Live 2021 on
win10 and Linux, when compiling the following file (arara is just here
to simplify the process):


% arara: latex
% arara: dvips
% arara: ps2pdf: { options : [ -dALLOWPSTRANSPARENCY ] }
% arara: clean: { extensions : [ aux, log, dvi ] }
\documentclass{article}
\usepackage{pstricks}
\pagestyle{empty}
\begin{document}
\psset{gridfont=helvetica}
\begin{pspicture}[showgrid](3,3)
\psdots[linecolor=blue,dotstyle=x](1,1)
\psdots[dotstyle=oplus](0.5,0.5)
\psdots[dotstyle=otimes](1.5,1.5)
\psdots[linecolor=red](2,2)
\end{pspicture}
\end{document}


The output obtained on win10 is correct, but the output on Linux
(fedora 43) is not correct and in both cases it compiles without
errors.

I did some queries in TeXSX and they suggested using the following line
in the `.ps` file:

So it seems to be a problem with the fonts and font maps used by `gs`
in TeX Live windows that are not directly available on linux.


Any way out of the way to correctly compile the file on Linux?


Attached are the images and the `.ps` file generated in both systems.
