List-Help: List-Post: List-Subscribe: , List-Archive: List-Unsubscribe: , Errors-To: emacs-devel-bounces+emacs-devel=quimby.gnus.org@gnu.org Xref: main.gmane.org gmane.emacs.devel:12669 X-Report-Spam: http://spam.gmane.org/gmane.emacs.devel:12669 BTW, I find that I can get better scrolling behavior with emacs/GTK if I set `redisplay-dont-pause' to t -- otherwise, if I e.g., hold down a scroll key (say C-v), scrolling updates the scroll bar smoothly, but the text window only gets updated when I stop scrolling. Any comment on this? [My processor seems to be fast enough to keep up when redisplay-dont-pause is t] Does redisplay do a better job of keeping up when Emacs doesn't use GTK? If so, it suggests that redisplay with GTK is much slower. The thing to do is investigate what is taking the time.
