--- Comment #8 from Daniel van Vugt <daniel.van.vugt at canonical.com> ---
The wobble is gone because hysteresis is always enabled (I hardcoded it to
enabled). That's not a change introduced by the patch though.

Moving in squares (when the finger moves in circles) is the same old problem
with the hysteresis algorithm, not a problem with the hysteresis magnitude.

That all said, I support the idea of committing attachment 137490. Just
remember to not close this bug.

Once we're using fuzz, perhaps it will be possible to tweak the fuzz (hence
tweak the hysteresis) for each touchpad externally, like libinput-model-quirks?
