Component question

[Bojan Smojver]

I filed a bug recently against remmina
(https://bugzilla.redhat.com/show_bug.cgi?id=820815) which on second
look would seem to be unrelated to remmina itself, but is rather a more
generic issue affecting Gnome. Essentially, some applications that used
to start their windows with the appropriate size in F-16 (even
proprietary ones like ICAClient), now in F-17 appear to be disregarding
the size of the window and opening in almost full screen mode (the
window takes the whole workspace, but is not actually maximised).

Does anyone know which component is normally responsible for this? The
window manager? Some library?

TIA,
