BTW, since ps2pdf is just a script, I could see with strace that
the following command was executed:

  /usr/bin/gs -P- -dSAFER -dCompatibilityLevel=1.4 -q -P- -dNOPAUSE -dBATCH -sDEVICE=pdfwrite -sstdout=%stderr -sOutputFile=out.pdf -P- -dSAFER -dCompatibilityLevel=1.4 chartest3.pdf

and indeed, I can reproduce the issue with this command (on
chartest3.pdf generated by pdflatex with TL 2021 installed).
