Hi, you may start here: https://github.com/p2rkw/xf86-input-mtrack/blob/master/src/gestures.c#L720 That one code branch is handling 'smooth scrolling', you may try reenabling scaling of speed vetor by time delta

Hi, I thought I fixed that, please set ScrollSmooth to 0 and then experiment with swapping ScrollUpButton and ScrollDownButton one more time.

I was about to write similar reply, but after few glances at the code I think it will work only with tap-do-drag drag. Worth to check anyways :)

Lookup for key/mouse bindings in your DE settings, bind mouse button 8 and 9 to show/hide expose.

Hi, Please set ScrollCoastDuration to 0, that should help with fast scrolling.

Was it always like that? Did this changed with some update? I suggest you to use "Hold and move" feature: I described it described in readme. Anyways I will what...

Scrolling with third finger on touchpad will be recognized as 3 finger drag. Thus mtrack will send configured button. Actual action taken depend on your setup. On my machine it...

Ok, I need your output of `xinput --list-props `.

Thanks. I suspect smooth scroll or coasting to have some impact on this. You can try to disable these and see does it change something or not.
