See https://bugs.freedesktop.org/show_bug.cgi?id=92091 If you look at the evemu recording with 2 fingers scroll, you will see that the kernel sends a slot and a tracking ID for the second finger, but it never sends the actual coordinates. Libinput ignores such slot (I'll check with Peter what we do in such cases when he will be back from his vacations) and this kills the 2 fingers scrolling. I believe the fix is worse than the original situation given that this also removes all gestures support we can have in libinput. And of course, with my turtle speed to test it, this patch is already in stable too (I am entirely at fault here :( ).
