Since you've built 27.1 --with-cairo, I guess youʼre picking up
different fonts (or your previous fonts were bitmapped ones, which
Cairo no longer supports, or youʼre now using the X font backend for
some reason).

'C-u C-x =' output from both builds would help confirm that.

Do you have any 'font-backend' settings in your .emacs, or .Xdefaults?
