This problem is indeed caused by installing GTK 3.10 (from 14.04 or elsewhere).
libgtk-3-0 3.10.6-0ubuntu1~~saucy1 [origin: unknown] This is the problematic package. Downgrade this package (and other upgraded packages depending on it) to 13.10 packages and the problem is fixed. I don't know if this is a problem with the package itself and also occurs in 14.04 (unlikely) or if it's just the combination of 13.10 and some 14.04 packages. ** Changed in: unity Status: New => Invalid ** Changed in: unity (Ubuntu) Status: Confirmed => Invalid -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to unity in Ubuntu.

Even stuff like "quit" or "about libreoffice". Using the keyboard shortcuts to access the items works though and it's possible to open sub-menus but nothing in them is clickable. This happens with several other apps like Gnome Terminal, Sublime Text (3 party package) and shotwell. The imagage viewer has the first menu working but not the other. Firefox seems to work. The single menu of nautilius works too. I found a smiliar bug against Libreoffice but maybe it's a different problem. https://bugs.freedesktop.org/show_bug.cgi?id=73794 See the attatched screenshot.
