Well, it's not a Wayland and KDE Plasma specific issue.
Slow scrolling occurs on both X11 and Wayland sessions of both KDE Plasma and Gnome DEs..

can confirm the issue.
it's been a problem for as long as i can remember and i don't think it's OS related.

the technical bit:
settings are grouped inside a grouplist control and scrolling inside a grouplist control has never worked properly with a mouse.

I had the same issue and the scroll issue disappeared. Still don't know the trick after a half day, but I did "modprobe logitech_mouse_module", and I ran nvidia-xconfig, anyway. Hopefully it helps one to the right direction.

Current modules:

usbhid     65536  1 hid_logitech_dj
hid        143360 4 usbhid,hid_generic,hid_logitech_dj,hid_logitech_hidpp

Current xorg.conf:

Section "InputDevice"
    Identifier     "Mouse0"
    Driver         "mouse"
    Option         "Protocol" "auto"
    Option         "Device" "/dev/input/mice"
    Option         "ZAxisMapping" "4 5 6 7"
EndSection

Last xorg.conf (before nvidia-xconfig):

Section "InputDevice"
    # generated from default
    Identifier     "Mouse0"
    Driver         "mouse"
    Option         "Protocol" "auto"
    Option         "Device" "/dev/psaux"
    Option         "Emulate3Buttons" "no"
    Option         "ZAxisMapping" "4 5"
