Description Jean-François Fortin Tam 2015-11-04 00:13:22 UTC 
With GNOME 3.18.x on Fedora 23, scrolling with the right edge of my Thinkpad's touchpad doesn't work properly anymore. Instead of scrolling as smoothly as my finger moves, it scrolls smoothly and "jerks" around every 10-20 pixels or so, making it impossible to read text in gedit while scrolling for example. This also occurs in gnome-control-center's mouse testing UI.
Comment 1 Jean-François Fortin Tam 2015-11-04 00:28:08 UTC 
Oh, I need to specify that this does not (perceptibly) happen if you're scrolling fast with the touchpad, only if you're scrolling slowly.
