It appears we have flaws (incorrect multiplication) in both QtMir and our default System Settings:

1. QtMir is multiplying vscroll events by 15, and forgetting to un-multiply them before passing them down to clients.

2. Our default System Settings (the unlabelled second slider under Mouse & Touchpad) seems to have a default scale of around 0.5. So the vscroll values of 15 from QtMir get converted to +7/-7 and that's what Mir apps receive in Unity8 instead of the expected +1/-1.
