If mode line updates change the height of the mode line (because of descenders, or images or stuff like that), it is conceivable that something happens with the display, though likely not on all lines at once. Even for line number updates, if you use line numbers with a non-constant height (old-style numerals). So it seems like it would at least appear prudent to check whether the mode line dimensions changed or something like that, or check just what lines the mode line might overlap. -- David Kastrup, Kriemhildstr. 15, 44793 Bochum _______________________________________________ Emacs-devel mailing list Emacs-devel@gnu.org http://lists.gnu.org/mailman/listinfo/emacs-devel
