After I have updated Manjaro, touchpad started acting up. It works fine until I try to use multi touch, especially 3 finger gestures when it glitches and cannot use for like 10 to 20 minutes when it starts working again.
I’m on wayland using libinput. I have recorder libinput test here youtu.be/wX8levb2o_8
It seems that there is ghost touch being active all the time.

I tried googling solution, but I’m not skilled enough and I don’t know what to do.
Update:
I have left laptop on suspend for the night and It seems to be working now. Using libinput debug-gui it seems fine, but this is output I get

See wayland.freedesktop. org/libinput/doc/1.20.1/touchpad-jumping-cursors.html for details
I went to the link provided wayland.freedesktop. org/libinput/doc/latest/touchpad-jumping-cursors.html and recoder touchpad inputs (don’t think I attach file here, but if it’s needed I’ll find a way)
bumping this, since I’m still experiencing this problem. I don’t know where to look at for solution, and I don’t know what could be causing this problem.
Please help
