Good evening,
I may ask about my issue since it has been bugging me out since I installed KDE.
Touchpad acceleration is nice. Except when its not. Sometimes acceleration deaccelerates, and its annoying because everytime I get used to the fast cursor, but then suddenly the cursor is slower. Acceleration is doing its job since I can reach the corners without lifting my finger but it is noticeably slower. Its like it’s easing in and out when I move my cursor.
I can trigger this sometimes when I scroll; after scrolling the cursor gets slower. Then I have to wait indefinite amount of time to get the usual mouse acceleration.
This is usual mouse acceleration:

This is eased in-out / weird acceleration:

It has been pretty consistent with the scrolling triggering this. More often than not i get the weird acceleration.
