</div></div>I'm guessing this is a bug I finally tracked down yesterday. :-)<br>

Can you re-test with current libxcb from git master?<br>
<br>
I'm a little surprised you had success with current Xlib/XCB though. I<br>
have some fairly hefty patches I'm testing right now (`ico -threads<br>
16` is running on another desktop) to squash several Xlib threading<br>
bugs. Have you noticed the Xlib version of your code dying sometimes<br>
with assertion failures, or hanging?<br>
<br>
Thanks,<br>
