This worked! I was only having the issue with Firefox, so I’m glad I didn’t try altering any config files and only edited the about:config. Thank you for finding this. Oh, and I’m not on a framework (yet), but I keep an eye on the forum for when I do finally get my batch 5. For anyone wondering; I’m running Fedora 34 on a Macbook Air 2013.
I’ve tried this same fix but it only seems to work for certain apps. Scrolling in Firefox works great now, but scrolling in the “Files” app and others does not. I’m guessing that this is based on how the apps are made, but still frustrating to never know if your scrolling will work or not.
