--- Comment #4 from Pierre Fortin <[email protected]> ---
Wired mice; none of which have fast or freewheel mode:
OK - no-name MO-5013U
OK - Sunsonny T-M30
OK - Dell MS116t1

...but keep reading...  :)

I also have a really low-end Logitech M215; but it uses a dedicated receiver,
and doesn't have fast scroll, so I won't waste my time with it. I expect it
will act as the wired mice and the M510v2.

** Only these two mice have fast/freewheel mode.

[++] indicates the mouse this UR was paired with in the respective package.
[**] slow scrolling issue in both freewheel and ratchet modes; BUT fast
freewheel scrolling (via finger flick) works fine.
[1] Down scrolling is as reported. However, scrolling this bug report in
Firefox Nightly 101.0a1 is smooth in both directions, as in any other
application, including within oocalc's font/font-size selectors,
Gallery>Diagrams, or anything else that is scrollable in oocalc.
[2] No freewheel mode on this one.
[3] This mouse can be paired with 3 receivers -- any combination of UR and/or
Bluetooth to 1, 2 or 3 computers; there's a selector to switch between hosts.
[4] The Logitech M510v2 wireless mouse does not have fast/freewheel mode, so it
acts just like the wired mice. 
[5] Scrolling down fails in both freewheel and ratchet modes.

HTH...

LOL... I'm reminded of "be careful what you ask for".  Seriously, the only
common denominator (so far) is fast/freewheel capable mice.

Ruminating...

This reminds me of interrupt handlers that don't re-enable interrupts fast
enough; but will keep processing queued ones without have to re-enable because
there's still work to do...   

Does calc have code that is "uninterruptable" (some form of software lock)?

But darn, this is a super fast machine...  

Other than positive/negative values for direction, scrolling should be using
the same code paths...  hmm...  are they?
