Public bug reported:
Randomly, sometimes at boot and sometimes later, the scrolwheel of my Logitech
MX Master 3s becomes oversensitive, registring 1 short flick as 5 to 7 long
flicks.
The workaround is running solaar (the problem appears whether solaar is loaded
at session start or not), entering the MX Master 3s section, unlocking and
enabling the "Scroll Wheel Resolution" switch, and re-disabling it.
This is what I get from 1 short flick when the problem occurs:

And this is what I get from 1 short flick when it does not occur, or after
using the workaround:
