Transparency Issue on MacTex 2021, previous fix does not work anymore for XeLaTex

Question

Recently there was a fix to the problem related to transparency issue on pstricks+ Mactex 2021, which is actually related to Ghostscript ver> 9.53. It modifies /usr/local/texlive/2021/texmf-dist/dvipdfmx using some line on dvipdfmx-unsafe.cfg

The fix as suggested by Herbert Schulz in: PStricks doesn't compile anymore since MacTeX 2021 upgrade on Mac M1

worked for me few weeks ago, and still works for latexTRmk.

But XeLatexTRmk engines (in TexShop) does not give the intended result.

I have the following simple code

%%%%%%%%%%%%%%%%% fix PSTricks' transparency setup %%%%%%%%%%%%%%%%%
\begin{filecontents}[overwrite,noheader]{pst-fixtransparency.pro}
  /.setfillconstantalpha.bak /.setfillconstantalpha load def
  /.setstrokeconstantalpha.bak /.setstrokeconstantalpha load def

\end{filecontents}

      dup .setfillconstantalpha .setstrokeconstantalpha} def
    /.setshapealpha {
      dup .setfillconstantalpha .setstrokeconstantalpha
      true .setalphaisshape} def
  }
}

The screenshot of the result using XeLatexTRmk is

While the intended result using LaTexTRmk, commenting the XeLatex specific lines like mathspec etc; will give:

So I tried copy-paste my code to overleaf.com and using XeLatex there (the menu indicates that TexLive 2021 is in use), and the result is fine as above (of course, I also uploaded all the Times fonts).

Using TexMaker and XeLatex engine in TexShop would produce the same result as following:

While using TexMaker and opted to view the PS file (instead of PDF), will invoke generating pdf files on Preview.App and the result is inconsistence (at some point it achieved fine result, otherwise error filename.ps cannot be converted to pdf)

Using command-line

xelatex -output-driver="xdvipdfmx -i dvipdfmx-unsafe.cfg -q -E" -no-pdf filename.tex

also not working.

I have also checked that all my packages are up to date.

This problem appears on all documents using pstricks, the picture produced is sometimes correct, but it always changes the background to white (no transparency)

Picture produced using tikz is fine.

Is there any fix for this? I'm guessing this only effects OS X users.

Thank You.

Answer 1

It is easier to run it with lualatex, which, of course, needs some time for the calculation, but it doesn't use GhostScript and creates directly the pdf:
