Same with "M-x grep RET" and in another cases. This was fixed as a special case in compile.el in 2014: ;; Turn off deferred fontifications in the compilation buffer, if ;; the user turned them on globally. This is because idle timers ;; aren't re-run after receiving input from a subprocess, so the ;; buffer is left unfontified after the compilation exits, until ;; some other input event happens. (set (make-local-variable 'jit-lock-defer-time) nil) However, removing that does not remove all fontifying, but it seems to happen only after the compilation process has ended. So I'm not sure -- there seems to be a general problem here, but is it something that should be fixed? Or is it up to individual modes (like compilation mode) to switch delayed fontification off? There's probably not a lot of these modes that fontify process output on-the-fly. -- (domestic pets only, the antidote for overdose, milk.) bloggy blog: http://lars.ingebrigtsen.no
