commit e4c9a71088d3c921ab01f90dc1117d8db1cdb997
Author: Pavel Sanda <sa...@lyx.org>
Date: Mon Jun 5 22:45:14 2023 +0200
Use ps2pdf -dALLOWPSTRANSPARENCY by default.
Ghostscript 9.52 breaks transparency, for some time -dNOSAFER
workaround worked but since 9.53.3 -dALLOWPSTRANSPARENCY should
work. Tested on 9.53.3.
