Next question: does it reproduce easily in "emacs -Q"? It does. As soon as I disable scroll-bar-mode, menu-bar-mode, tool-bar-mode and blink-cursor-mode. It goes like this: 1. 'emacs -Q', disable stuff. 2. 'C-x p f', visit lisp/emacs-lisp/smie.el. 3. Search for something rare using 'C-x p g' (e.g. for "Coq-specific", but not necessarily). 4. Press 'q' to exit the search. On step 3 or 4, the title bar will get updated noticeably faster than the frame configuration changes.
