Bug#742028: xserver-xephyr: -screen not respected

[Christophe Troestler <Christophe.Troestler@umons.ac.be>]

Package: xserver-xephyr
Version: 2:1.15.0-2
Severity: normal

Dear Maintainer,

When I launch Xephyr,

    Xephyr -screen 300x300 :1

only a small window is created, definitely not a 300x300 one.  xprop
though reports that

    WM_NORMAL_HINTS(WM_SIZE_HINTS):
                    program specified minimum size: 300 by 300
                    program specified maximum size: 300 by 300

I use the nvidia driver 331.49-1 but I had no problem before.
xnest works without problem.

Best,
C.
