This is very hard to describe, but it drives me mad so I'll try.
I experience this bug with Firefox, Thunderbird, Synaptic.
I don't with i.e. Thunar (GTK2?)

Reproduce:
* open one of those applications mentioned above
 (in Firefox it is helpful to open a page with many/large hyperlinks, so the
  hover effect described later on is easily visible)
* minimize that window (no matter if with hotkey or Minimize button)
* trigger compiz scale
* pick that window
 > window is visible like it was previously, except:
 > titlebar buttons are desaturated
 > titlebar buttons react on hover, but aren't clickable
 > titlebar menu (app menu) is visible on hover (1)
 > do whatever you would do in that window (click, scroll, type)
* minimize window with hotkey
 > window is invisible, but not minimized
 > no former underlying windows can be clicked, instead mouse cursor changes
   exactly as if 'minimized' window would still be on top
 > clicks are passed to that 'minimized' window

(1) at this point, clicking any of the menu topics WOULD bring window to normal state

Now, the only way to get back to normal:
* trigger compiz scale
* pick minimized window in question
* there, click any item in titlebar
 > window is in 'regular' state now
* minimize

In ccsm, neither of the options in "General Options" > "Focus & Raise Behaviour" have an effect for me, nor do those in "Scale" or "Scale Addons".

For me, the only way to fix this behaviour was to follow the description in this question's answer [[http://askubuntu.com/questions/621167/problems-with-minimizing-and-closing-windows-in-ubuntu-15-04|askubuntu.com/questions/621167]]:
* install Unity-Tweak-Tool
* "Unity" section > "Switcher" > check "Switch between minimized windows"

This extremely annoying if you work with several browser windows, a thunderbird window and others.
