Flickable's mouse wheel scrolling keeps going inertially (past the location I want to scroll to)

Hmm, maybe the problem is just QtMir speeding up/amplifying mouse wheel events a bit too much:

src/platforms/mirserver/qteventfeeder.cpp:

            const QPoint angleDelta = QPoint(hDelta * 15, vDelta * 15);
            mQtWindowSystem->handleWheelEvent(timestamp.count(), angleDelta, modifiers);

which then makes for a high scrolling velocity that takes a while to finish.

Looks like the problem may get worse (even higher speed) when Ubuntu Touch gets Mir 0.21 or later with this fix:

Nope, Mir 0.22 on the phone didn't change this bug.

In other news, it appears the excessive inertial scrolling is app-specific. In the dash it scrolls to the top/bottom instantly on the slightest wheel movement. In System Settings however (main panel), wheel scrolling is better behaved and doesn't scroll anywhere near as far. Possibly still a bit too fast though.

Status changed to 'Confirmed' because the bug affects multiple users.

Erm, fixed for mouse wheels now (?!)

New issues with touchpad scrolling only, while I'll log separately.

Sorry, still happening badly in the Apps scope. And only sometimes in the Background settings.
