Indeed I was still using org-mode in a local straight repository checkout predating this fix in upstream: https://git.savannah.gnu.org/cgit/emacs/org-mode.git/commit/?id=65def05f6c6f7ce706a0116ad666c86eb0ecdae2 lisp/ox-beamer.el: Fix face definition * lisp/ox-beamer.el (org-beamer-tag): Fix face definition. Updating my local repo fixed it. Thinking about it, I probably should stop using straight at all for org-mode, as I seem to update Emacs more often lately than the straight repos. In this setup the old checkout from straight shadowed the correct code in upstream Emacs. Another interesting way to shoot my own foot :/ Thanks! Detlev
