This is usually due to jit-lock-stealth which does font-locking in the
background when Emacs is idle.  Try (setq jit-lock-stealth-time nil)
in your .emacs (that's what I use and I recommend it if you're running on
battery or if your CPU is not dedicated solely to Emacs).

It's odd that those would make any difference.
