The same question regarding pstricks's transparency was discussed in pgf's and pstricks's opacity is not working
Unfortunately, after upgrading to Texlive 2023 and Ghostscript 10.02.1, the same old issue we've discussed in this previous Q & A about pstricks's transparency appeared again.
Additionally, this time the changing of command in TexStudio from ps2pdf %.ps %.pdf to ps2pdf -dALLOWPSTRANSPARENCY %.ps %.pdf or ps2pdf -dNOSAFER %.ps %.pdf doesn't solve the problem, as had happened before.
Any ideas?
Edit (23/12/2024): The issue related with XeTeX, which I'm using.
