I am using Acer A315-57G with Arch linux 6.11.5-arch1-1, KDE plasma, libinput version 1.26.2, Wayland
My issue is rather straightforward, the touchpad either works normally (sometimes, seems very random) or feels like it is like a car in ice track (moves slow, doesn't stop immediately when I stop, seems like has a lag of 300-400 ms between my finger and the display,). It also jumps randomly when I chaotically move the touchpad. Here are some other information may be related to the issue:
1. Mouse works perfectly, and normal. I never had an issue with it.
2. Whenever I use "disable touchpad" physical button on my laptop keyboard several times in a row (5-6 times). The touchpad returns to normal. The issue comes back after a random time though.
3. If I move with touchpad chaotically rapidly, and during that press the disable button and enable it, the cursor goes crazy. It jumps everywhere, sometimes even presses left/right click (digitally, of course) and returns to its either normal, or old sluggish version after 5 seconds.
4. I did not have this issue before in the same system with arch. I encountered this issue because of unknown reasons and I still experience it often.
5. The issue sometimes goes away by itself.
6. The touchpad is usable, but is very annoying and stressful to navigate with it.
From some of the logs I have found in my system, (I don't remember, sorry), the touchpad was giving "libinput 1.26.2 jump bug" and sent me to this website:
https://wayland.freedesktop.org/libinpu … rsors.html
Even though it may be related, my issue seems more complex.
I would love to provide any command/log outputs, I am not that experienced though, just give me the commands.
Thank you!

Hi again. The issue is still there and it it is very hard and stressful to use the touchpad. What could be the issue here? Any suggestions? Thank you!

I was pointed here by someone in my topic about an incredibly similar-sounding issue that I am having. The effects of the problem are almost identical (sluggish pointer control, gets worse after rapid movement), except I'm getting it with my physical mice on my desktop PC running Plasma, but under X11 instead of Wayland. May I ask what your CPU usage looks like when the lag is occurring? When I'm having it happen, one CPU core gets immediately pegged to 100% usage.
EDIT: User ReDemoNBR suggested it might be a bug in the kernel, and surprise! switching to the LTS kernel fixed both their and my own mouse lag issues. Please try that when you get the chance.

I have tried linux-zen and linux-lts kernels (currently on 6.6.63-1-lts), and issue persists for me. I also tried to usb-boot to the mint, and the my touchpad still acts the same there.
This bug or whatever is not affecting my CPU usage.
I am confident this issue is software related. The first thing is, the touchpad works normal sometimes, then it starts to acts sluggish again. It also scrolls, right/left clicks randomly if I move chaotically. Moreover I did not have this issue in the same system, hardware in the same linux setup before. I guess some update (or custom configuration? I did not touch anything about my touchpad) broke my touchpad.
I have tried downgrading the kernel, libinput and still it doesn't fix my problem.
