[XeTeX] Ghostscript 9.53

[jfbu]

Hi,

Recently I updated Ghostscript and it is now at 9.53.3

It seems xelatex compilation stalls and possibly never
completes on some documents which I have been given
and use pstricks. Here is a shortened console output

$ xelatex foo.tex 
This is XeTeX, Version 3.14159265-2.6-0.999992 (TeX Live 2020) (preloaded format=xelatex)

which looks good but then I get about a hundred

   **** See .setfillconstantalpha/.setalphaisshape for the improved solution


which are emitted slower and slower and slower
until finally I have to kill the job

^C(see the transcript file for additional information)
Error 2 (driver return code) generating output;
file foo.pdf may not be valid.

With the latex+dvips+ps2pdf route, compilation succeeds
but the ps2pdf steps output abouts 220 warnings as above to stdout

Also I have to use the -dALLOWPSTRANSPARENCY else the ps2pdf crashes,

I did not know whether to post this to tlbuild or here.
I did a quick check of archives of past few months.
Quite probably the Ghostscript thing has been discussed probably
one or two years ago.
I understand my install is double-faced.
On the texlive side it is darwin-legacy.


However I felt there was a specific xetex issue because
I have to CTRL-C with xelatex, not with ps2pdf.

Regards.
