Personally I haven’t. While Linux is imperfect, choosing the right distro makes the rest of the experience straightforward. And with it’s whole complexity, I find Linux more user friendly than Windows. Even driver issues, broken shadow file ownership and KDE specifics only made me more confident about my choice to use Linux after I solved everything.
TBH the only time I’ve ever got involved with autoscroll was when a user accidentally clicked the wheel, and got “stuck in a funny mode” and the mouse was no longer working. I’m not sure how many regular users know it even exists - there are a lot who still don’t even use the scroll-wheel at all.
In Linux, the scroll-wheel works as I expect it to anyway, so I’ve never wanted to change it.
