I'm using the synaptics driver. Although it doesn't seem to be supported right now, I never had any similar issues when using it on other laptops. Anyway, sometimes whenever I touch the touchpad the cursor starts moving and clicing everything without any movement from my fingers. This laptop has a touchscreen that works fine, they don't seem to be conflicting, since disabling it won't stop the touchpad from going haywire.
% xinput list
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ ETPS/2 Elantech Touchpad id=14 [slave pointer (2)]
⎜ ↳ Atmel Atmel maXTouch Digitizer id=11 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]

↳ Asus Wireless Radio Control id=6 [slave keyboard (3)]
↳ Video Bus id=7 [slave keyboard (3)]
↳ Power Button id=8 [slave keyboard (3)]

↳ ASUS USB2.0 Webcam: ASUS USB2.0 id=10 [slave keyboard (3)]
↳ Asus WMI hotkeys id=12 [slave keyboard (3)]

Kinda lost on where to look next, do you guys have any advice? Thanks a lot!

I'm guessing it's an issue between the new versions of X and the now unmaintained synaptics.
My suggestion would be to switch to libinput instead.

Ok, I just tried your suggestion, now using libinput with the synaptics pkg removed, the problem persists, nothing has changed. Also, if I have an usb mouse plugged in, the mouse works as expected, just like the touchscreen, the cursor only starts misbehaving if i touch the touchpad.
Edit: some xinput test output of me just resting my finger on the pad for a sec or so:

I have a similar Asus laptop with same touchpad (Asus Vivobook S551LN). After some time, Elantech touchpad started to behave strangely: basically the right click is always pushed, so every time I move the pointer it drags and selects everything in its path.
In my case I already verified it is an hardware problem (same thing happens with windows 10). I tried to fix it on the hardware side, but I didn't succeed. The only software workaround I found is to remap button keys with xinput.

the right click
it drags and selects.
You mean the left click?
Although I considered the possibility of hardware damage, I just installed arch on this machine and the touchpad was working properly in windows. Actually it was slow as shit, the scrolling sucked (linux's synaptics driver's momentum scrolling is sooo fast and smooth) and the only thing configurable about it was the scrolling direction... but anyway, no misbehaving. Also, I got the touchscreen working pretty much just like it does in windows, mail me if you need any help with that.
