It is true that the Evdev drivers emit other keycodes compared to the
'legacy' drivers.
I'm using this command to specify the correct mapping ("-rules evdev" is
the important part):

    setxkbmap -rules evdev -layout us -variant altgr-intl -option ctrl:nocaps,compose:menu

I'm not sure if this is enough for KDE. I see 'Option "xkb_rules"
"evdev"' in your log, so the correct mapping should already be used?
Maybe KDE reverts this somehow. FWIW, when I press the arrow keys in xev
I see the following (correct) output:
