For short and quick scroll gestures, those that should only trigger a few lines of scroll the pointer acceleration is wildly unpredictable. Since we average the motion of both fingers it's hard enough to intuitively predict what the motion will be like. On top of that is the small threshold before we start scrolling, so some of the initial motion gets swallowed before we accelerate, making the next motion even more unpredictable. The end result is that multiple seemingly identical finger motions cause wildly different scroll motion. Drop pointer acceleration for two-finger and edge scrolling. This makes short scroll motions much more predictable and doesn't seem to have much effect on long scroll motions. Plus, in natural scroll mode it really feels like the content is stuck to your fingers now. Go wash your hands. https://bugzilla.redhat.com/show_bug.cgi?id=1249365 Signed-off-by: Peter Hutterer <peter.hutterer@who-t.net> Reviewed-by: Hans de Goede <hdegoede@redhat.com>
