I had similar problem after upgrading from Ubuntu 14.04 to 18.04 (Ubuntu
4.15.0-42.45-generic 4.15.18). I noticied that when I shut down wifi the
touchpad lag is gone. Also when I turn wifi on again, the lag doesn't
re-appear. After restarting my laptop the lag is back again.

Does it support 3/4 fingers in Windows?
Does it work under -72 as @abbot says?
@abbot,
Can you also try linux kernels between -72 and -78? We can narrow down the
changes we need to look at.

Hmm, try this:
$ sudo sh -c 'echo -n "elantech" >
/sys/bus/serio/devices/serioX/protocol'
Replace X with correct serio number.
File an upstream bug if this doesn't work.

What need you?
Do you think this random problem may be related to ubuntu not detecting the
touchpad as touchpad if not as generic mouse?:

A quick google shows that Hantick sells rebranded Elan touchpad (in
Chinese though) - that's why I asked this question.
Anyway, please give Linux kernel here a try:

We actually tested these computers with Windows 10 and the touchpad does
not skip after several days of use.

Unfortunately the problem continues.
Whenever this happens the pointer moves top of screen completely, or to
the top right corner. The tocuhpad does not work if I try to move the
pointer with my finger, that is, until I do not separate my finger from
the touchpad.

Hello,
Thanks Kai-Heng, with "imps" and "bare" the touchpad is crazy.
I had defined the other parameters tried to fix the error. But I have
deleted and put only psmouse.proto=exps
Now the touchpad works, but I still try to see if the error returns,
because I think "exps" is normal mode...

Please try 'psmouse.proto=bare', 'psmouse.proto=imps' or
'psmouse.proto=exps', without any other kernel parameters.
