just with my normal .emacs. I'll start bisecting. I don't see "Narrow" in the modeline after the above. But a momentary narrowing does happen, and it comes from here: safe_run_hooks_maybe_narrowed (Qpre_command_hook, XWINDOW (selected_window)); [...] safe_run_hooks_maybe_narrowed (Qpost_command_hook, XWINDOW (selected_window)); The function on pre-command-hook in my case is tooltip-hide.
