Now that's interesting. I'm curious to see if there's any kind of hardware difference between that R13s that funcion correctly and the faulty ones.
Could you please run a hardware scan app like HWiNFO (https://www.hwinfo.com/download.php) on one laptop that has the problem and on one that doesn't? Perhaps Acer used different touchpads during the manufacturing of the R13.

Clik here to view.
Mine is apparently made by Elan Microelectronics. I found out that Elan makes touchpads for a lot of different brands (Acer, Lenovo, HP...), and that there are problems all over the place — it's not just an Acer thing. Strangely enough, a lot of users seem to encounter the 'cursor jumping issue' only when the laptop is plugged in, but I'm encountering it when running on battery too.
