It could mean XCB is just a little faster than Xlib. ;-)

The real question is whether those Expose events, etc., show up if you
run the loop again a little while later. If you never, ever get them,
and your XCB-using code makes pretty much the same sequence of requests
as the Xlib-using code, then I suppose it could be an XCB bug.

You can tell by using either xscope or ethereal to watch the responses
coming back from the X server. That may tell you that those Expose
events aren't actually being sent to your XCB-based code. Then you might
ask why not...

Hope that helps.
