My FW12 is working great for what I’m using it for but the trackpad for some reason goes bonkers whenever even a little bit of sweat or moisture gets on it. By “bonkers” I mean that the cursor starts jumping erratically within a random radius and usually in a recognizable pattern.
This behavior stops when I close the machine and then open it up again, i.e. I am able to use the trackpad “normally” again for a few swipes before enough sweat gets on there again that it starts being weird again. So maybe this can be fixed by introducing some code in the trackpad driver code that detects if the trackpad is rapidly jumping around in wacky directions and resets it accordingly, just like what happens when it’s initialized when the laptop gets opened.
I have a similar issue. It only started to show up a couple months ago (I’ve had this F12 since September, and another one from August to September that had to be sent back due to it’s own issues), kept getting worse, and then seems to have become less frequent after I removed and reinstalled the input cover (but it’s still happening)
I have this exact issue. It pops up randomly and I haven’t benn able to isolate it. Seems to have a mind of its own. I’m not sure whether this is a “sweat” issue as I’ve had it occur to me when my hands were perfectly dry. It also doesn’t go away when I wipe the trackpad clean. I’m suspecting a bug in the palm rejection algorithm. Goes away without a trace after your close and open it back up.
I’m experiencing something similar. Does trying to click with the cursor just cause the cursor to jump and bounce back to its original position? Sometimes, letting go of the trackpad (without attempting to click) causes the cursor to jump in some direction, usually up or down diagonally.
I don’t think it’s only related to sweat since I don’t use the laptop with wet hands. Restarting didn’t seem to fix the issue right away either.

I’m not entirely sure what it is, but I too have noticed a “flaky” trackpad. It seems to behave erratically. Not sure if it’s getting worse or if I’m just noticing it more, but I do feel like it is very imprecise. Sometimes it doesn’t register the movement when I’m very clearly moving my finger, sometimes it doesn’t register when I tap it without raising my finger high enough. I would’ve said it’s a me problem, but I’ve used other laptops and even on the budget ones, I’ve had more consistent experience. I’m not entirely happy with the keyboard overall. Sometimes when I don’t press the keys deep enough when I’m typing quickly, they will not register a keypress. Maybe my unit is faulty?
Thank you for sharing the workaround of putting the laptop to sleep and then waking it up again. That seems to be a pretty consistent fix, as annoying as it can be sometimes! Usually my trackpad behaves the way described, jumping around wildly, but today it manifested as left-click always registering as right click. Sleep/wake (without even brushing off the trackpad) fixed it too, so fingers crossed this can be worked around in software later as you suggest! Maybe some kind of calibration / zeroing happens on wake?
That’s exactly what I’m thinking – perhaps this is an easy fix: just make the touchpad reset itself every couple of seconds, if and only if the user isn’t currently touching it.
