SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 5.21.4 KDE Frameworks Version: 5.81.0 Qt Version: 5.15.2 Graphics Platform: Wayland
Sorry, I was using Arch while reporting this issue, but it affects neon unstable. Operating System: KDE neon Unstable Edition KDE Plasma Version: 5.21.80 KDE Frameworks Version: 5.82.0 Qt Version: 5.15.2 Graphics Platform: X11
Cannot reproduce, which means that this is caused by your touchpad sending bad scroll data, or Libinput interpreting your touchpad in a way that sends us bad scroll data, or Qt interpreting the above as bad scroll data. Nothing we can do about it in KDE land, sorry. :(
