That's probably this specific commit.

Could you try playing with the acceleration option (-a) of moused? I also
think the sensitivity is a bit over the top at the moment. I'm getting good
results with -a 0.75 and am considering making that the default (changing the
distance calculation in psm, actually). But maybe that's still too much?
Suggestions welcome :-)

I'm not seeing that here. Does the behaviour change depending how much of
your finger stays on the pad while dragging?

This I have seen, but not very often, and always when I've just put moused in
the background after getting sick of its verbosity in the foreground :-o

By default, the touchpad behaves like a simple two-button mouse and does the
scaling and accelerating itself. When you activate the special features, you
also have to do all the 'standard' magic yourself. The documentation, while
very good, unfortunately doesn't specify exactly which magic values the
internal logic uses, so it's a bit of guesswork still. :-)
