OK my findings were only found in Chrome and Slack. Slack is a Chromium App. and so I think this issue is with the Slack and Chrome developers. not with Apple. Possibly this could be a fault in Electron framework, but Facebook Messenger did not have an issue. escalating to Chromium and Electron.

How is this happening to you? Chrome?, what about other apps (are they up to date)?

It is unclear your instructions. I could not find your instruction process. Also I get this only in Chrome and Slack, but on Razer mouse too.

Same

Tell us how it happens. I have noticed it on apps running Chromium, or Chrome specifically. What happens is scroll stops and you have to wiggle the mouse to get it working again, and scroll a second time. It is Apples fault that the developers have this issue, and apple is not addressing it because it is perceive as a Chromium bug, but really no app should be glitching in this way Slack as an app seems to have the issue, I bet if I looked harder Slack would be built on Chromium.
