Performance seems to be improved, but still noticeably worse than when the tool-bar is disabled. For instance, the tool-bar seems to have an impact on the slow scrolling that people have been discussing on and off for the last couple of months. To reproduce: 1. emacs -Q --eval "(setq scroll-conservatively 10)" 2. C-h n 2a. M-x tool-bar-mode RET 3. C-n (press and hold down, causing continuous scrolling) When 2a is omitted, there are occasional pauses in scrolling. When the tool bar is disabled, scrolling is much smoother.
