3 finger swipe gesture breaks 2 finger scroll + os palm detection

[chalda]

Describe the bug

If Alttab gesture is set to 3 finger swipe, this somehow breaks the interaction between the built in OS palm detection with 2 finger scroll.

Its ignoring the palm detection and treating it as another finger, so even a light touch from your hand prevent any scrolling until you release. But more annoyingly, depending on settings can make your focus/input jump all over the place.

very annoying, actually spent so long today trying to figure out why the palm detection seemingly stopped working, guess ill switch to 4 fingers and see if that helps

Hi,

Thank you for sharing this issue. I was able to reproduce.

Looking at the code in TrackpadEvents, I see that the OS gives us the info about which touches become "resting". It's probably possible to improve on the current swipe detection.

#4020 may also help with this issue

Thank you

@lwouis 4 fingers seems to have helped in short term
Is it possible to have the os make the determination of what type of gesture it is and filter out bogus input

Appreciate you btw. Great project.

PS Have some ideas for interesting features but they might be out of scope for a utility

@lwouis hmm found that 4 finger swipe gesture fires on 4 finger spread for desktop

I've improved swipe recognition in many ways in v7.14.0. Could you please try it out, and let me know if it helps?
Thank you 🙇
