In general I like the idea of having 3.16 in vivid, as I already have
some packages that require it.

I noticed a couple of issues when testing it on GNOME Flashback session
with Metacity (all these may actually be bugs in Metacity, not new Gtk,
but they didn’t happen before):

* All non-CSD windows have a white border around the window (but not
  its top part). See the attached gnome-terminal screenshot for example.

* When using gnome-screenshot, its “flash” (white rectangle on the area
  being screenshotted) does not disappear unless gnome-screenshot process
  ends, which makes it very hard to actually use gnome-screenshot.

I will investigate both these issues later when I have time.
