Hi, I realize only now thanks to mail of Akira and also testing by a friend on a system with older Ghostscript that the file I reported problems with actually is not XeTeX compatible even with older Ghostscript.
I focused on gs 9.53.3 due to all warnings But my friend reports compilation is very slow also with older gs (I don't know the version) Then when compilation completes the animation in the pdf is broken. At my locale, compilation also finally completes after 2 to 3 minutes. And the pdf animation (from animate package and pstricks code) is even more broken. (this might be the 9.53.3 effect). In brief, my alarm was unwarranted as the problem existed earlier. Best, Jean-François
