I doubt there is much to do on distribution side. As fallback mode is dropped from support of GNOME (see https://wiki.gnome.org/ThreePointSeven/Features/DropOrFixFallbackMode), newer version GNOME/openSUSE will not even ship with it. So just no one is doing anything about fallback mode anymore.
A possible quick fix is to use command line tool: xkill. I also suggest to try out GNOME 3 (non-fallback mode), and to have a GNOME 2-like feel, you can find a lot of useful extensions on https://extensions.gnome.org/, including a "force quit extension". Also in future GNOME/openSUSE, there will be an officially bundled extensions pack that offers a better GNOME 2 experience. See https://help.gnome.org/misc/release-notes/3.8/, many extensions in the Classic pack are available for openSUSE 12.3 (which includes GNOME 3.6) and are installable from the above gnome extension site. In case, you would like a more authentic GNOME 2 style, there are also two GNOME forks: 1. Cinnamon (fork of GNOME 3), needs 3D graphics support. 2. MATE (fork of old GNOME 2), _no_ 3D support required. However these are not included in openSUSE 12.3, you can install them from unofficial repos from http://software.opensuse.org/ though. Hope these help.
