My setting is that mouse wheel scrolls by 3 lines. This really means 3 lines of stuff in dolphin, gwenview etc. In plasma however, it means 3 PIXELS! Scrolling in folder view, kickoff, widget explorer etc. is unbearably slow.

I can confirm it. But it seems that mouse wheel scroll setting do not affect to scrolling in Plasma: any values from 1 to 12 lines do not change anything in Plasma scrolling — it still the same slow. And seems like that affected not only Plasma, but also any Qt Quick applications: at least Discover, Systemsettings in Sidebar view, KTouch, MuseScore...

There is a workaround in one of our QQC2 implementations, but we can't use that everywhere.

Qt 5.10.1 solves this problem. Thanks.
