I have two Tumbleweed machines with very similar configurations – both running the latest snapshot with KDE Plsama 5.17, both utilizing Wayland, etc and one will let me scroll in Evolution but the other will not. I can scroll without issue in Firefox, Chrome, Libreoffice, any KDE app on both machines – the issue is specifically Evolution.
I’ve poked around the Evolution preferences and see nothing that might impact scrolling so I’m not sure how to troubleshoot this one.
