--- Comment #3 from Peter Hutterer <peter.hutterer at who-t.net> ---
I suspect it's this seqeuence here:

Debounce detection is based on timeouts, but here the time between the fake
release and the next press is 16ms vs the 12 libinput currently uses. If you
can, grab libinput from git and modify DEBOUNCE_TIME to 17ms. See if that
helps consistently.
