Title:
  Unity behind windows (Z-Index/Z-Order problem)

Status in Unity:
  Confirmed
Status in “unity” package in Ubuntu:
  Confirmed

Bug description:
  After Login, there sometimes is a problem with Unity (= Dash +
  Launcher + HUD), where Unity appears to have the false
  Z-Order/Z-Index.

  In this cases i can't realy access Unity, with maximized programs.
  Sometimes normal (=not maximized) windows appear in front of the Dash
  or Launcher (see the screenshot).

  This typically is just after the Login. After i somehow fixed it
  (clicking Workspace-Switcher or pinning a window to the Front), the
  problem stays fixed for this (X-Server-) session.
