Can reproduce. Seems like an issue specific to the custom slider object in this KCM.

kcm/VolumeSlider: fix scroll

stepSize was not set to disable tickmarks. However scrolling also
depends on stepSize. qqc2-desktop-stlye implements scrolling via
increase()/descrease() functions, which default to steps of 0.1
when stepSize is not set.

Override them to get scrolling working without setting stepSize.
