Which queue did you observe it entering? With Xlib/XCB, I can interpret
your report as meaning either that you saw xcb's read_packet function
pull the event off the wire, or you saw Xlib's process_responses and
handle_event functions pass that event off to _XEnq.

I started trying to reproduce your problem, but I don't have any XInput
devices configured (as far as I know) and working out how to set up the
evdev driver to treat my three mouse devices separately, instead of
using /dev/input/mice, is more than I have time for tonight. I can at
least try to diagnose remotely if you'll provide more information.

Yay, validation from a new extension developer! We sure hoped XML-XCB
would make the task of implementing new extensions easier. We'd happily
take your XML and include it in the xcb/proto repository if you'd like.

Your post at
made my day. Thanks. :-)
