I'm not good at email communication. This is my first attempt to submit a bug report to Emacs. Maybe I could add CC to emacs-orgmode@gnu.org on the recent email that shows all my emacs current state info. ---------- Forwarded message --------- 发件人: Ihor Radchenko Date: 2022年5月21日周六 09:33 Subject: Re: [BUG] when open a large org file, emacs get stuck and show a warning "org-element--cache: Unregistered buffer modifications detected" To: imymorror wang imymorror wang writes: > sorry . the whole warning text is (twice): > #+begin_quote > Warning (org-element-cache): org-element--cache: Unregistered buffer > modifications detected.

It appears that something is editing the buffer either before or after loading Org mode. Can you share the values of change-major-mode-hook and org-mode-hook? Also, do you deliberately drop the CC to emacs-orgmode@gnu.org and prefer the conversation to be not public? Best, Ihor
