Actually I think this bug might be tangential to the precision problem in QtMir.
QtMir appears to maintain a little smooth scrolling to a precision of roughly 0.067 mouse wheel ticks. But touchpads commonly have a precision of more like 0.00025 equivalent mouse wheel ticks.
So both problems are real. It's possible I have tied them together here in a single bug erroneously though.
