I can try (once more) to see if it changes anything if I drop those links, but
the list currently seems to have an appropriate order:

But that would just be the xcb plugin. The host applications will still be
linked against {OpenGL,AGL}.framework, at least as long as I just build the xcb
platform plugin as an alternative for a Qt install that uses Cocoa by (and as
the supported) default.

That's good to know, thanks.

That does seem relevant indeed.

The fact that there's a BadValue error is unlikely to be Qt's doing, nor the
deadlock in XLockDisplay. But is there nothing Qt applications could or should
do to handle the window-close event in such a way that the issue is avoided?

I'll see if installing the latest port:mesa changes anything.
