(Horizontally) Maximized and Fullscreen Windows activated in different workspace move to primary display

[Horacio Durán]

Prerequisite: multi monitor and multi workspace environment

1) Move to a secondary workspace and open your default browser (firefox, chrome...)
   window, then move it to the secondary monitor¹ and maximize it (or full screen it).
2) Move to the primary workspace and in a terminal launch:
   xdg-open http://ubuntu.com
3) Now move back to the secondary workspace

Expected:
4) The browser loads Ubuntu homepage and is still in the secondary monitor (where it
   used to be)

Actual:
4) The browser loads Ubuntu homepage, but it has been moved to the primary monitor.

I attached a video where this is displayed by showing that the browser maximized is in monitor 3 of workspace, I go to different workspace, click a link, upon returning the window is now in the laptop monitor.
This only happens when the window is maximized.

[1] primary monitor could change in compiz (and not match the xrandr one), then you might need to try to figure which one is yours.

This bug was fixed in the package compiz - 1:0.9.12.1+15.10.20150805-0ubuntu1

---------------
compiz (1:0.9.12.1+15.10.20150805-0ubuntu1) wily; urgency=medium

  [ Alberts Muktupāvels ]
  * Change icon size back to 48px in application switcher plugin. (LP:

  * New rebuild forced.

  [ Dmitry Shachnev ]

    #971051, #1465647)
  * debian/compiz-gnome.gsettings-override: Remove unityshell from
    active plugins, and add switcher. (LP: #1469086)

  [ Eleni Maria Stea ]
  * It fixes the 3d windows plugin. Problem: The 3d clipping is
    performed in viewing space (modelview transformation) and should be
    done inside the shader when we use shaders otherwise the viewing
    space pipeline operations will be ignored. Compiz used to perform
    the clipping inside the td plugin using pipeline functions, then it
    was loading a generic shader program (no clipping operations) to
    render the windows and then it rendered the 3d quads around the
    windows using the pipeline (so these were clipped correctly). (LP:
    #1395697)
  * Sometimes the MultipleCubes, Automatic or OneBigCube option might be
    set although we are not in multimonitor. Modified the 3d windows
    plugin to check the number of monitors as well.

  [ Marco Trevisan (Treviño) ]
  * Window: add clientFrame(), to get the client-side decoration extents
    (LP: #1422768, #1436553)

    position (LP: #1475721)

  [ Martin Wimpress ]

  [ Stephen M. Webb ]
  * Fix a FTBFS when -std=c++11 is used. (LP: #1477654)
  * Fixed the Compiz manpage and --help message to agree with the actual
    command-line options supported. (LP: #1475508)
  * force Compiz to build using C++-11 (required by build dependency
    libgtkmm-3.0-1). (LP: #1477978)
