Yes, and I'm also not sure if this problem is related, though I guess it
could likely be.

Just install the "frame-fns" and "frame-cmds' Gnu Elpa packages.  Load
them in this order, then eval (enlarge-font 1).

(emacs-version) 
==>
"GNU Emacs 27.0.50 (build 15, x86_64-pc-linux-gnu, GTK+ Version
3.22.30)\n of 2018-08-29"

master build from today.  Debian Linux.  I have not configured fonts in
any way AFAICT.  Don't know much about this stuff.  I just noticed that
`enlarge-font' stopped working some days ago, and reverting to the
commit that has been mentioned made the problem go away.
`text-scale-adjust' works normally OTOH.

Anything else I can do?


Thanks,

Michael.
