This might be due to my setup (I'm using a custom, $HOME/.xsession to
start my window manager and some other stuff).  Anyway the problem seems
to be not too seldom, as gpg-agent -- which has the same problem of
being an daemon running an xclient (pinentry) on changing displays -- is
able to update not only the DISPLAY but XAUTHORITY, too.

Would it be that much trouble?  DISPLAY is already communicated to the
server and used, why would it be especially hard to do the same for
XAUTHORITY?
