Comment 7 for bug 929712

I believe this problem may not be exactly the same as the one it is set to duplicate. This involves context (right-click) menus, not global menu, in fact affected applications may not even use global menu at all (e.g. Skype or QtCreator from official QtSDK). Also the fix released for #775278 does not correct anything reported here and I didn't notice the probem described in #775278 myself as I don't usually minimize apps to tray.
