Some reddit users are experiencing this issue too: https://www.reddit.com/r/kde/comments/8u2g3q/touchpad_scroll_settings_getting_reset/
Comment 2 abugreporter 2018-10-14 16:40:10 UTC 
I have found a way to reproduce it 100% of the time: disabling and enabling touchpad using the dedicated keyboard key.
Comment 3 Julius B. 2018-10-26 12:12:50 UTC 
I can confirm the bug with Plasma 5.13.5-1 on Fedora 29 (see https://bugzilla.redhat.com/show_bug.cgi?id=1643460 for the downstream bugreport).

It also happens when plugging/unplugging a USB mouse.

$ kcm-touchpad-list-devices | grep TOUCHPAD
Name: Synaptics TM2911-001 Type: TOUCHPAD Use: Extension Pointer
Comment 4 Michał B. 2018-11-03 08:11:19 UTC 
Same for me. When I open touchpad settings on Kubuntu 18.10, after restart I see an information that data stored are different than shown in a dialog box.

When I reset and save settings it is being fixed.

Same happens here every time after unlocking the desktop.

Name: DLL0665:01 06CB:76AD Touchpad Type: TOUCHPAD Use: Extension Pointer
5.13.5 on Fedora 29

From this:
[761738.410] (II) event7  - DLL0665:01 06CB:76AD Touchpad: device removed
[761739.221] (II) event7  - DLL0665:01 06CB:76AD Touchpad: is tagged by udev as: Touchpad
[761739.221] (II) event7  - DLL0665:01 06CB:76AD Touchpad: device is a touchpad

seems like something gets lost on locking and after coming back settings are not applied.
Comment 6 Michael 2018-11-19 18:52:21 UTC 
Well, for me, it is a mouse/touchpad settings conflict. Setting "Inverse scrolling" to true in kcm's mouse setting "fixes" it for me.
Comment 7 Michał B. 2018-11-19 19:03:37 UTC 
Thanks Michael, it solves a problem also in my case.
Comment 8 Julius B. 2018-12-09 18:59:23 UTC 
Seems like this bug has been fixed in Plasma 5.14.0, see bug#395722. :)
