No, I haven't.  I upgraded from within my tmux session and suddenly all
my panes had junk in them.  I don't normally log out or reboot except
for kernel updates.

I would appreciate it if you'd work with upstream to get them to remove
the code that prints these messages.  There's no legitimate reason for a
shared library to print anything unless explicitly requested by the
calling application .

This would be less of an issue if fontconfig didn't reload config files
in existing processes.
