I don't know where and why GDK_CORE_DEVICE_EVENTS is set. Something
related to erratic scrolling behavior, but is known to break gtk xinput2.
It's in:
/etc/xdg/plasma-workspace/env/gtk3_scrolling.sh
with contents:
# see

if [ -z "${GDK_CORE_DEVICE_EVENTS}" ]; then
GDK_CORE_DEVICE_EVENTS=1
export GDK_CORE_DEVICE_EVENTS
