Public bug reported:

The pointer barrier event API we've patched in to libXfixes has moved
upstream in Xserver 1.14. However, the API has changed.

The barrier events and pointer release API is now in the input lib,
libXi as of version 1.6.99.1 . It should be reasonably easy to port to
the new API: Peter Hutterer's blog post¹ describes how to use it. The
main differences are that you need to add the barrier event mask to the
XI event mask, rather than window event mask, and that it now uses
generic events, so you need to allocate the event data before using it
and free the event data after using it XGetEventData/XFreeEventData.
