I haven't seen this at all -- interesting! Can you try doing it
plugged to power vs on battery? What variables are at play -- humid
weather? Humid hands?

We've found that unstable power supplies can make touchpads (on any
laptop!) behave rather erratically.

they should have the exact same tp.

Yes --- just swap the entire lower base assembly -- it's the same.
It'll be a bit confused as to the keyboard layout (it'll think it has
a mechanical kb, so for example frame key will stay on F6 rather then
be on top-right corner, arrow keys will be hopelessly confused...).

I can also send you touchpads.
