On Plasma 5.13 beta, on Wayland, the flat acceleration profile for the mouse does not work. I can select it in the mouse KCM module, but when I click "Apply", it selects "Adaptive" again.
Can confirm on Arch
Thank you both for reporting and confirming. Seems to be a simple copy-paste issue: https://phabricator.kde.org/D13270
