In most apps all menu items are gray / unclickable

In Libreoffice write for example all menu items in the gloal menu are gray and unclickable. 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.
