that's... strange. the code that looks at the speed setting is not called from
the two-finger scrolling code.

Can you confirm please:
At the speed where you notice the bumps, is the default speed in synaptics
faster or slower than libinput?

Can you observe the bumps in synaptics? They are most likely smaller but still
there, so watch closely, do you get 1-3 pixel jumps with synaptics when
libinput jumps a lot more?
