Found it! It turns out I was almost right. It wasn't the libs, it
was the composite extension in X.org which adds new visuals to the reported
list. Some apps don't deal with this very well.
Solution: Prevent X from enumerating the additional visuals. This
is done by setting the environment variable XLIB_SKIP_ARGB_VISUALS to 1.
Thus, 'xmms' could be launched by saying:
----
bash$ XLIB_SKIP_ARGB_VISUALS=1 xmms
----
The same approach gets GnuCash running at full speed, too.
