For the record, here's what the current work-around in Qt looks like:

#ifdef XCB_USE_XLIB
    if (!handled) {
        // Check if a custom XEvent constructor was registered in xlib for this
event type, and call it discarding the constructed XEvent if any.
        // XESetWireToEvent might be used by libraries to intercept messages
from the X server e.g. the OpenGL lib waiting for DRI2 events.
        Bool (*proc)(Display*, XEvent*, xEvent*) =
XESetWireToEvent((Display*)m_xlib_display, response_type, 0);
        if (proc) {
            XESetWireToEvent((Display*)m_xlib_display, response_type, proc);
            XEvent dummy;
            event->sequence = LastKnownRequestProcessed(m_xlib_display);
            proc((Display*)m_xlib_display, &dummy, (xEvent*)event);
        }
    }
#endif
