Comment 6 for bug 1749957

To fix that issue you only need to recompile compiz too. And that's enough.

However, then the tests fail because of a crash inside libglvnd at exit:

(gdb)

In fact when the nux windowthread is closed, and its graphic display is free'd we do a call to glXDestroyContext which leads to this crash because for some reason the dispatch->table is already free'd by something else (the driver?).

Getting rid of that line fixes the issue, but indeed isn't correct.

There's a comment on __glDispatchDestroyTable saying
    /*
     * XXX: Technically, dispatch->currentThreads should be 0 if we're calling
     * into this function, but buggy apps may unload libGLX without losing
     * current, in which case this won't be true when the dispatch table
     * is destroyed.
     */

Not sure if this is the case though, as it's quite cryptic to me.
