that issue started in vivid it seems
https://errors.ubuntu.com/problem/7feea27498d47b4914cf17674c927cfa0b0e1d7e

the date seems to correspond with 7.3.1+15.04.20150219.2 which added menus for unfocused windows

This bug was fixed in the package unity - 7.3.2+15.04.20150330-0ubuntu1

---------------
unity (7.3.2+15.04.20150330-0ubuntu1) vivid; urgency=medium

  [ Andrea Azzarone ]
  * Do not restore focus if a quicklist is opened during launcher key
    navigation. (LP: #932486)
  * Forward first key event that happens on top of the blank window to
    the lockscreen. (LP: #1308265)
  * Hide launcher to avoid damaging window when not needed. Also make
    sure that pressure effect works fine (previous fix has been reverted
    because of this!). (LP: #1301394)
  * Make sure scope_views_[filter.id] exists before using operator[] on
    it. (LP: #926979)
  * Make sure that signals are auto-desconnected when
    XdndStartStopNotifierImp is destroyed. (LP: #1432231)
  * Release pointer barrier if launcher is in lock_hide state. (LP:
    #1029114)

  [ Sebastien Bacher ]
  * use the new nautilus .desktop name (LP: #1436297)

  [ Stephen M. Webb ]
  * AP tests: accounted for arbitrarily-raised exceptions in checking
    scaled windows (LP: #1436095)
