I see this was reported on the pythonocc list November 13 two years ago:

The reply says this had already been fixed at that time in a newer version of python-xlib which was about to be released. Version 0.14, to which the port was just updated, is four years old, so doesn't include the fix. Maybe 0.15rc1, which was released two years ago, on November 14, the day after the question was asked, does. We usually only update ports to stable versions, but maybe in this case, since the developers of python-xlib are clearly being very relaxed about their release schedule, we should make an exception, if 0.15rc1 does resolve the problem. (Could you test whether it does?)
