Re: Gtk+ 3.3.7+ bugfix will BREAK Xorg (before 1.12) unless patch is applied

[Benjamin Otte <otte gnome org>]

Here's a heads-up on this patch: We've held up on applying this patch
to give developers a chance to get their servers fixed. But we want
this patch in 3.4, so it has now landed. So if you are running a GTK
>= 3.3.19, you need to have an up to date X server or you'll see weird
focus behavior.

A workaround exists: If you export GDK_CORE_DEVICE_EVENTS=1, GDK will
stop using XInput and use old-school X11 events, and that code path in
the X server doesn't have that bug.
