Comment 18 for bug 86103

For the record, the 1.0-1.1ubuntu2 version still does not fix the problem with other applications. For instance, commercial products like Neverwinter Nights still breask

21:15:51 /home/games/nwn$ ./nwn
nwmain: ../../src/xcb_lock.c:62: _XGetXCBBuffer: Assertion `((int) ((xcb_req) - (dpy->request)) >= 0)' failed.
Aborted (core dumped)

I've done the export LIBXCB_ALLOW_SLOPPY_LOCK=true and still it breaks. How can I get a version of libxcb or whatever which does not do the assertions. Or how can I bypass it (my prefered solution would be to bypass rather then not do it at all).

Even though it is a bug, it is a commercial product and they are not going to be pushing out bug fixes for this type of stuff.
