Laptop touchpad is laggy, slowish, jumpy and unreliable

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!
