Comment 53 for bug 185311

I've tried the different proposed solutions but none fixes the problem in my case. I still have sometimes the message:

../../src/xcb_lock.c:77: _XGetXCBBuffer: Assertion `((int) ((xcb_req) - (dpy->request)) >= 0)' failed.

when calling wxWindow::SetCurrent() on a wxGLCanvas object after it has been created.
The most promising solution seems to be the one here:
http://lists.freedesktop.org/archives/xcb/2008-March/003347.html
but it has still not be included in the last version of Xcb (http://changelogs.ubuntu.com/changelogs/pool/main/libx/libxcb/libxcb_1.1-1ubuntu1/changelog)

I hope the patches will be quickly tested Xcb updated...
