Tried all the way down to 1.9.2 (from https://salsa.debian.org/xorg-
team/lib/libinput/tags), as well as 1.10.5. The issue for me on the
trackpoint seem to be present on every version there.

I also think I notice a pattern, it seems that the "jump" occurs after I
stop going from some coordinate A to B, right as I apply pressure on the
trackpoint to move my cursor backwards. However, the jump occurs from B
away from A, which is not expected and make it seem laggy/unintuitive.

Additionally, I noticed that the trackpoints with 1.9.2+ libinput are
significant faster than 1.8.4.

I have a slow mo video of this that I can upload in the morning.
