DISPLAY=:1 is short hand for connecting via the Unix socket
"/tmp/.X11-unix/X1".
That will only works if both the X server and applications run in
the same base filesystem.
If you chroot the application and not Xephyr, then the application
cannot found the unix socket.
It is possible to make Xephyr (and all the other Xservers) listen
on a TCP socket like in the old days with:
Xephyr :1 -listen tcp -ac &
This will allow you to use "DISPLAY=127.0.0.1:1" for your x
applications. (And no other IP than 127.0.0.1 on OpenBSD.)
