Bug#836972: gnome-control-center display issues identified.

Control: found 836972 3.21.90-1
Control: tags 836972 = pending

Hello Jean-Marc, Đặng Duy Sơn.

I'm happy to tell you that Michael Biebl notified me about
http://bugs.debian.org/836939 which is another symptom of
the same underlying issue where he had already identified
the cause.

The problem is a mismatch between gnome-desktop3 and mutter.
Both need to be either 3.20 or 3.21/3.22.

I've just committed a change that should guarantee that
gnome-desktop3 3.21.x won't install together with mutter 3.20
which should resolve your issue.

Hopefully mutter 3.21.x et.al. migrates to testing today, but
if not then you should be able to resolve your issues by
installing mutter + gnome-shell + dependencies from
unstable/sid.

Thanks for your feedback.

Regards,
Andreas Henriksson
