(This bug report unfortunately got no response at the time.)

I'm not sure what font that is, but I tried this in Emacs 28:

# apt install fonts-stix
emacs -Q -l /tmp/stix.el

> Run emacs with no other customizations, using -Q -l <file.el>. The

I get

    ftcrhb:-GOOG-Noto Sans CJK KR-normal-normal-normal-*-39-*-*-*-*-0-iso10646-1 (#x2D)

in the initial frame, which I guess just means that I don't have Source
Code Pro.

I then `C-x 5 2', and query the new frame for the font it's using, and
it's the same one.

So I don't seem to be able to reproduce this problem in Emacs 28 -- are
you still seeing it in more recent Emacs versions?
