Jumpy Scroll Using TrackPad Across All Applications

I have a ThinkPad P52s that has jumpy scroll. It seems to be happening everywhere (chrome, firefox, xed). I'm using xorg, not Wayland.

Laptop info:
CPU: quad core Intel Core i7-8650U (-MT MCP-) speed/min/max: 1437/400/4200 MHz
Kernel: 6.1.9-arch1-1 x86_64 Up: 2h 8m Mem: 4590.9/31946.4 MiB (14.4%)
Storage: 1.86 TiB (3.1% used) Procs: 334 Shell: Bash inxi: 3.3.24

libinput version: 1.22.1
Desktop Env: Cinnamon 5.6.7

Here's what it looks like:  https://streamable.com/5wpznm

I've tried the below:

- ran

sudo libinput debug-events --device /dev/input/event6

, but not seeing anything odd happening when the scrolling jumps
- installed xf86-input-synaptics (and then uninstalled)
- create a synaptics config file (/etc/X11/xorg.conf.d/70-synaptics.conf) (and then removed)
- running

xinput list-props 11

, i'm getting:

    libinput High Resolution Wheel Scroll Enabled (349):    1

- i've set the below to the low and high range (10 and 50)

    libinput Scrolling Pixel Distance (347):    15
    libinput Scrolling Pixel Distance Default (348):    15

- flipped these toggles

    libinput Accel Profile Enabled Default (342):    1, 0
    libinput High Resolution Wheel Scroll Enabled (349):    1

...and have logged out each time but haven't been able to fix it.

I've also tried downgrading libinput to 1.18, but that made my keyboard, trackpad and mouse inoperable as I mention in this post: https://bbs.archlinux.org/viewtopic.php?id=270121

Any suggestions?

Re: Jumpy Scroll Using TrackPad Across All Applications

Try using the LTS kernel or downgrade the latest kernel.
I also had similar problem with two finger scrolling, it was working in one way but not the other (up vs down).
Found the thread https://bbs.archlinux.org/viewtopic.php?id=283979 which suggested to boot into a LTS kernel or downgrade to a kernel before the issue happened.
