Bug#843642: gnome-terminal: Scrolling with touchpad combines smooth and rough movement

[Johannes Dahl]

Package: gnome-terminal
Version: 3.22.0-3
Severity: normal

Dear Maintainer,

When scrolling in Gnome Terminal using a high resolution method like two-finger
scroll on a touchpad or button scroll with a trackpoint, for every few lines of
smooth movement, there is a jump of another few lines. The expected behaviour
would be one or the other, preferably smooth scrolling, but not both.

I speculate that Gnome Terminal reacts to both real XInput 2.1 scroll events and
emulated button 4-7 events.
