Thanks for the bug report. I've seen similar issues with some mice over
the years and each time for me it was a hardware problem as my mouse
wheel had worn out or had manufacturing defects. So please try a
different mouse or two...
Please also try uninstalling 'imwheel' (and reboot) to see if that
solves the issue.
If the problem is still occurring then it sounds like it might be
specific to Xwayland apps. So please try logging into 'Ubuntu on Xorg'
instead.

Title:
Mouse scroll is discarded in specific cases, for specific programs
Status in Ubuntu:
Incomplete
Bug description:
Behavior observed on Jammy Jellyfish. Using a Microsoft Model 1923
mouse with incremented (clicking) scroll wheel.
When running certain programs, my mouse scroll wheel exhibits odd yet
highly repeatable behavior.
This behavior is not present in the Ubuntu mouse tester, or in simple
programs like the text editor.
However, for more complex programs like Brave Browser or a game like
Beyond All Reason, the behavior is always present, and always
predictable.
I'll describe the behavior in Brave, although similar behavior is
observed in other programs. I load a new web page. I scroll down one
click. Nothing happens. I scroll another click. The page "jumps" two
clicks down. After this, scrolling down one click at a time works as
expected.
If I reverse direction and scroll up, the behavior repeats. Scroll up
one click. Nothing happens. Scroll up a second click. The page "jumps"
up two clicks, and then scrolling up works as intended.
This behavior is not present in Linux Mint. It may sound silly, but
this bug was enough to make me migrate permanently to Mint. Scrolling
happens often and when the UI responds only part of the time to
repetetive input, each "surprise" where the response is not as
expected takes just a tiny, tiny chip out of your sanity. By the end
of a day it's quite annoying.
I hope someone is able to track down the problem. I'm a fan of Ubuntu
and have used it for many years.
Cheers
