If you use Gtk applications which recently passed from Gtk2 to Gtk3, as for example the reader of RSS feed Liferea, you were able to notice that scrollbars (elevators) do not behave any more in a usual way: when we click above or below the scroll bar, instead of causing(provoking) a scrolling of a page, the bar(helm) moves now all at once(of a sudden) in the place where we clicked.

To restore the standard behavior, it is enough to publish(edit) or to create the file ~ / .config / gtk-3.0 / settings.ini and to place these two lines there:

[ Settings] gtk-primary-button-warps-slider = false

This proposal did not work at my home(with me).

Concern not only Mageia (2014/12/29):
http://trisquel.info/fr/forum/trisquel-7-revenir-%C3%A0-lancien-comportement-de-la-barre-de-d%C3%A9filement

With Trisquel 7, the behavior of the scroll bar (that we also name "elevator") is changed (except in Thunderbird), before, when we clicked a lower point than the zone of this one representing the place of the window, this one came down(fell) from (almost) a screen (that is the equivalent of the touch [Down page] of the keyboard), what allowed to read the continuation(suite). Now, that goes to the precise point (proportionally) of the page where we are, for example, if I click at the very bottom, I find myself at the bottom of the page.

That's a gtk+ 3.0 behavior change

Use right click instead of left click for pgup/pgdown.

Comment 4 M GT 2015-04-09 15:32:48 CEST

To restore the standard behavior,place :

gtk-primary-button-warps-slider = false

in

/etc/gtk-3.0/settings.ini instead ~/.config/gtk-3.0/settings.ini

and use left click for pgup/pgdown.
