Bug#744249: libgtk-3-0: gtk 3.12 breaks usability by forcing client side decorations on X11

[Vlad Orlov]

I guess I've seen the same bug in Synaptic's package properties window
in the current Debian Testing.

It's impossible to resize that window by holding the left mouse button and
moving the mouse. I always end up with the window properties menu
(which is usually invoked by right-clicking on the window title) showing up.
