Git bisect actually tells me that xdvipdfmx started misbehaving from
the same commit that caused gs issues:

017927b4d63c317e1fc450be2537ccc058072538 (HEAD)
    Author: Han-Wen Nienhuys <hanwenn@gmail.com>
    Date:   Fri Jun 5 20:36:42 2020 +0200
    Unify calling convention for command-line and API GS use

Jonas reverted some parts of that with MR !148, but that particular
issue was left unaddressed.  That affects xdvipdfmx svn/20190225,
which is shipped with Fedora 32, and with a more recent build from the
2020 texlive release (20200315). (Now, I haven’t been able to
reproduce it on LilyDev so other libraries may be a factor as well.)

It already took me many hours to find the eight regtests that trigger
this, but there are also many snippets and NR ly blocks, which I won’t
be able to track down :-/
