Steps to reproduce:
At some time since my last update (to 110.b3, I'm not sure what I had before it) my trackpad's scrolling stopped working in Firefox. It works fine in other applications.
Most noteworthy: scrolling does not work in Firefox settings screens, where, as far as I'm aware, any extensions can't affect things. I've also tried disabling them all, with no change.
When I go to "Help -> Troubleshooting Mode" though, scrolling works everywhere.
So... I'm not sure what this implies, but it doesn't seem like it'd be triggered by any of my local changes. Is there any other information I can help collect, or perhaps narrow it down to "my install is weird, not expected to be a problem for others"?
To add some more info, from further experimenting:
- keyboard scrolling works fine, as does grabbing and dragging the scrollbar.
- verified it still happens with all extensions disabled, including after closing and reopening Firefox.
- I don't believe I have any about:config changes at all. Certainly none in the past few months if not over a year.
- This happens in literally every UI I can find with a scrollbar:
- Every website, all top-level browser settings screens, about:config, "customize toolbar", new tab page.
- Developer tools as well.
- If I have too many tabs, I can't scroll through them (the left/right buttons work though).
- If you have any other unique UI, please let me know! I'll try it too.
- Stable firefox (109) works fine.
Middle-click-and-move-mouse-to-scroll does work!
It appears to work everywhere, but I have not checked very thoroughly. And of course I can't use it on tabs when the list of tabs overflows.

The Bugbug bot thinks this bug should belong to the 'Core::Layout: Scrolling and Overflow' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

Yep, that sounds like the same issue. Disabling hardware acceleration and relaunching fixes it.
Thank you!
er. didn't mean to close that as invalid - it gave me an error when I tried to close it as a duplicate of 1798014, so I went back and submitted it without that... and it somehow interpreted no-resolve-selected as "invalid".

@reporter, Are you using X-mouse ?
If so, this is duplication of Bug 1798014.
If not, this seems a different issue.
I am, yes. I suppose I should've tried disabling that earlier...
Anyway: with hardware acceleration enabled + with x-mouse shut down: scrolling works again. So it's just hardware + x-mouse that's the bad combination.
