Bug#673824: gnome-shell: Same/similar problem.

[David Balch]

Package: gnome-shell
Version: 3.12.2-3
Followup-For: Bug #673824

Dear Maintainer,

I am also encountering problems with gnome-shell when using multiple monitors (with a single monitor, the problem does not appear).

With two monitors, screen refresh is very slow, and gnome-shell CPU use at least 70%.

Running glxgears repors a higher framerate that the visible refresh rate of the window.
