I am using tabbar and some settings for smooth scrolling which seem to conflict with each other in a weird way. Here is a minimal init.el file:
(package-initialize) (setq mouse-wheel-scroll-amount '(1 ((shift) . 10) ((control) . 30))) (require 'tabbar) (tabbar-mode t) (setq mouse-wheel-progressive-speed nil)
With these settings, if I now try to scroll a moderate length (600 long lines) tex file in the AucTeX mode, it jumps back, i.e. if I scroll, say, up, and look at the percentage bar, it goes 70,69,68,67, and then jumps back to 70,69,68,67,... If I move the point somewhere else and start scrolling again then it scrolls ok for a while but then again starts cycling around. Disabling tabbar mode makes the issue disappear. Is there maybe a setting that could prevent tabbar from affecting this scrolling behavior in such an annoying way?
I'm on OS X 10.12.5, Emacs 25.2, and the issue appears the same way if I use mouse or touchpad.
UPD. thanks to @lawlist's comment, it suffices to open the tex file and just set
header-line-format to a non-
nil value. The updated minimal init.el file now is
(setq mouse-wheel-scroll-amount '(1 ((shift) . 10) ((control) . 30))) (setq mouse-wheel-progressive-speed nil)
