This is due to the globalized minor mode re-adding itself to the
`post-command-hook' in `,MODE-cmhh'. This only happens when the
major-mode changes in some buffer. In other words, you will run into
this only when trying to switch buffers or use the minibuffer. You can
still navigate the file, i.e. `next-line' is usually fine for me.

from the patch I attached earlier.
