Hi!
After update from 33780 to 33810 Scrolling on my Logitech Ambidexter trackball does not work.

My /etc/X11/xorg.conf.d/10-libinput.conf

Section “InputClass”
Identifier “Marble Mouse”
MatchProduct “Logitech USB Trackball”
Driver “libinput”
Option “ScrollMethod” “button”
Option “ScrollButton” “9”
Option “ButtonMapping” “1 8 3 4 5 6 7 2 9”

EndSection

xinput show that button work.
~ $ xinput --query-state 13
2 classes :
ButtonClass
button[1]=up
button[2]=up
button[3]=up
button[4]=up
button[5]=up
button[6]=up
button[7]=up
button[8]=up
button[9]=down
ValuatorClass Mode=Relative Proximity=In
valuator[0]=715
valuator[1]=808
valuator[2]=0
valuator[3]=0
