Comment 6 for bug 74008

from the bug on bugzilla.g.o:

gnome-screenshot does not assume anything: the window border are included only
if the "include-border" GConf key is set to TRUE, or command line argument is
given.

the problem is that the common path used by the include-border option doesn't
seem to work with compiz, so "include-border" is not honoured.

gnome-screenshot tries to find the current window using the _NET_ACTIVE_WINDOW
X property and then, if 'include-border' is set to TRUE, it walks back the
window chain until it finds the window frame.

I don't know why compiz doesn't do the reparenting, and neither understand why
it can't behave like every other window manager; if compiz authors wish to
share how gnome-screenshot should fix this misbehaviour, I'm all ears.
