If I do the following in this running Emacs: C-x C-f /tmp/empty-file.txt M-: (insert (propertize (make-string 20000 ?x) 'display "foo")) Then hit RET a couple of times, and then type any key (like `d'), the mode line starts saying "Narrow". If I hit it again, it switches off, and then hitting it again switches it on again. But if I try to reproduce this from -Q, or even with my .emacs, it doesn't happen. So something has to be present... in some other buffer...? for this to start happening, and I don't know what.
