Re: xfwm4 crashes on NetBSD 9.99.17 (was "Re: firefox dumping core after NetBSD upgrade")

I do not have MesaLib installed on this v/b guest at all.

I bisected xfwm4.xml to try to find out which setting was causing the
problem. I didn't bother to read it first, as the result was obvious:
..

So the problem is that on first invocation xfce4 sets use_composing to
true, even if composing is not available or not functional.
