SUMMARY KWin (or libinput?) seems to take the sum of the individual finger speeds instead of the average, so when pressing down a touchpad (clickpad) with more than one finger, the cursor moves faster. This affects software with right/middle-click panning and using context menus with a single click, but it doesn't make them unusable though, just mildy annoying STEPS TO REPRODUCE 1. Place more than one finger in the touchpad 2. Move the fingers in the same direction while pressing down the touchpad OBSERVED RESULT Cursor moves faster the more fingers you place EXPECTED RESULT Cursor moves at the same speed regardless of the finger amount SOFTWARE/OS VERSIONS Fedora Kinoite 41 KDE Plasma Version: 6.3.0 KDE Frameworks Version: 6.10.0 Qt Version: 6.8.2
Can confirm. KWin doesn't know how many fingers are down when you just move the cursor though, please report this at https://gitlab.freedesktop.org/libinput/libinput/-/issues
Turns out this is actually intentional, according to this commit https://gitlab.freedesktop.org/libinput/libinput/-/commit/6664144611dce94ae42e0e88495d3955f5823de8 You're supposed to move only one finger instead of both, might open an issue anyways since there's probably a better solution to that
