SUMMARY Horizontal scrolling on a mouse, e.g. with tilt scroll wheels, can't be kept non-inverted while inverting vertical scroll. STEPS TO REPRODUCE 1. Invert scrolling. 2. Scroll horizontally. OBSERVED RESULT There's only one setting "Invert scroll direction" that covers both vertical and horizontal scrolling. EXPECTED RESULT There should be two separate settings, one for vertical and one for horizontal. SOFTWARE/OS VERSIONS Linux/KDE Plasma: Debian 12 (available in About System) KDE Plasma Version: 5.27.5 KDE Frameworks Version: 5.103.0 Qt Version: 5.15.8 ADDITIONAL INFORMATION The scroll tilt *can* be rebound using our mouse's software to have right be left and left be right, but it'd be nice to keep them the conceptual right way around.
...Well that's not great. I poked at xinput to see whether there were separate scrolling direction properties to fiddle with there, found only one "natural scrolling" setting, and then found https://gitlab.freedesktop.org/libinput/libinput/-/issues/195. It looks like libinput got an upstream issue for allowing inverted scrolling on one axis but not the other, and closed it wontfix because effectively "who needs that". -- Topaz
