Ubuntu 13 Maximized Windows Problem

[tecknomage]

REF: Ubuntu 13.04 running GNOME Fallback (aka GNOME Classic) environment

After upgrade found Ubuntu 13 has a problem with maximized windows in the GNOME environment.

Again, with ANY window *already* maximized, the [Close][Minimized][Maximize/Unmaximize] buttons at window corners do NOT work.

In GNOME Fallback I can use right-click the Task-Bar entry and use the functions in the *context menu*, so I select [Unmaximize]. Now the [Close] and [Minimize] buttons on the corners work.

But verified that if I use the [Maximize] button afterwards, the problem is back.

Here are my findings.

System Config :

OS : 13.04 (Unity, gnome 3.6)
Driver : Nvidia Latest Proprietary
Themes : Ambiance

These steps will reproduce the issue :
1) Install Fresh 13.04
2) Install gnone-classic (fallback)
3) Install CCMS
4) Enable Static Switcher
5) Install Unity Tweak Too
6) Set Window controls to right side instead of Left Side
7) Open any application in Maximized mode. If Applications open in non-maximized mode, then open the app, maximize it, close it and then reopen it.
8) Try to close the application using Window Control in Right side.

You will notice that The application does not have focus at all, and if you try to close the app, it will simply close any maximized windows in its back. Basically, clicking the title bar actually shifts focus to the application behind it, instead of the the one in front.

So far I have found 2 workarounds :

1) Get a lower version of Compiz source and compile and install. In some forums people have left instructions on how to do it.
2) Install one of Mediterranean Themes. Is you use one of these themes, the bug vanishes magically.

Here is what I think :

It is a Bug either in Compiz or the Ambiance Theme settings itself. Or some issues which get activated with the combination.
So if someone can compare and diff between the themes Ambiance and Mediterranean, the issue or fix could be figured out.

Also, please notice that when using the Ambiance theme, The Applications and Places text in the top panel are attached to each other and there is no gap between text of both. Whereas in Mediterranean they are separated which is how it should be.
