I'm not sure if this is KDE specific, but every once and a while I will randomly either lose either 2-finger scroll or tap-to-click on my touchpad.
Logging out and logging back in always fixes the issue. I'm just curious to figure out which process seems to be messing up so I can restart it myself instead of logging out.
I'm using a Cyprus touchpad which I know uses "Synaptics" driver.
