[Bug 1659610] Re: compiz scale: restored windows can't be minimized properly


apport information

** Tags added: apport-collected compiz-0.9 ubuntu

** Description changed:

  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?)
  * 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
  This extremely annoying if you work with several browser windows, a
  thunderbird window and others.
  For me, the only way to fix this behaviour was to follow the description in this question's answer http://askubuntu.com/q/621167:
  * install Unity-Tweak-Tool
  * "Unity" section > "Switcher" > check "Switch between minimized windows"
  I just learned that I could also enable "Application Switcher" in CCSM. For aesthetic reasons I didn't. For stability reasons I didn't because in the past often enough 'unnecessary' options in CCSM rendered my system unusable.
  In this very special case I didn't because Unity's app switcher is nice and working for minimized windows, so why enable another one?
