Pre-scroll lag from touchpad for 2019 MacBook Pro

Hi fellows. Anybody observed (in your MacBook Pro) that, if the machine is left to idle for a while, that there will be a lag from the first moment the scroll is physically administered onto the touchpad, and when the document/webpage reaches the location it is supposed to scroll till? But after that first scroll, there is no lag whatsoever.

Example: first scroll after machine idle, the cursor has to "jerkily catch up" to the location in the page where it is supposed to scroll to, instead of "gradually" gliding to that spot. See 0:03s, 0:28s, 0:46s(observe my fingers' movement on the touchpad and how the page jumps):

This happens across browsers. May I know how I can rectify this?
