I'm not intimately familiar with the details, but basically there are
evil hidden events that you're not aware of that are used by the
direct rendering infrastructure. Xlib hides these (by sneakily passing
them to somebody other than the caller of XNextEvent()), XCB does not.
IIRC, the OpenGL libraries don't even provide a documented entry point
for the events, so you can't pass them by hand.

See, for example: https://bugs.freedesktop.org/show_bug.cgi?id=42131
