maybe unrelated to your issue, but my touchpad stopped working properly
after using a GRUB theme installation script, on a Clevo NV41MZ, Ubuntu
18 to 22
what solved the issue for me was updating the /etc/default/grub file by
changing this line :
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_os_na

I sometimes get the jitter too but I've yet to find a reliable way to
reproduce it.
I also get low speed jitter where the packets reported to the interrupt
handler don't have new x and y coords but the pressure is changing. This
results in jerkiness at very low speed which I can reliably reproduce
I can confirm this is still very much an issue on elementary 6 based on
Ubuntu LTS 20.04, also includes jittering and jumping every so often
even with the kernel peramiter workaround mentioned in other comments

I've no clue as to how to reproduce it. It seeming starts at random, and

never horizontally) while being
I don't know if it's related to the jitter you experience but with these
tweaks the cursor is really precise now (read both issue as they are

I've submitted a fix to the input maintainers. I've been running this
since the 23rd and it seems to be fine. No need to pass any params to
the driver to change the protocol or anything like that.
It's yet to be reviewed but since it's a single line change I'd hope
it'll get look at at some point
