Dmitry,

This September saw updates in both GhostScript (9.53.0, now 9.53.3) and
pstricks-base (3.01).
It turned out this combination is the cause of the error you have encountered.

Update announcement of pstricks-base 3.01 [1] says:

    This version has a modified pstricks.tex|.pro for GhostScript versions > 9.52

However, it does not work with ghostscript 9.53.x in perfbook's use cases.

So, one workaround would be to downgrade ghostscript to 9.52 [2].

Another option would be to downgrade pstricks-base to 2.90 (2018/12/17)
(or similar [3]), which is the version in Fedora's current TeX Live package.
But note that an old version of pstricks-base might be incompatible with
the up-to-date upstream TeX Live.

It may sound strange but pstrics-base 2.90 works with ghostscript 9.53.x
as far as transparency composition is not concerned.
Perfbook's figures don't use transparency composition.

GhostScript's compatibility-breaking "security" updates have caused a lot of
troubles these days...

Hopefully pstricks-base would catch up gs 9.53.x soon.

        Thanks, Akira
