--- Comment #3 from Nate Graham <nate at kde.org> ---
Ok, I can reproduce this.

I'm pretty sure that it happens because on Wayland, we're scaling all input
events to approximate a scroll speed setting, which Libinput doesn't provide.

We would have to de-scale the scroll events in Plasma to ensure a consistent
scroll speed for things that should stick to the logic of one mouse wheel
"tick" equaling one change in the thing being scrolled
