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.
