Ubuntu :: ALT+MiddleClick (resize Window) Doesn't Grab Foreground (top) Window

If you don't know, users are able to quickly resize windows using the "ALT+MiddleClick" key shortcut/combo. Basically, hold the ALT key, and mouse middle click and hold on a window. Move the mouse around, and it will resize the window for you.

STEPS TO REPRODUCE:

1) Open a single Window.

2) Near the bottom-right-hand corner of the window, ALT+MiddleClick and drag. It should resize. Great. It works.

What Doesn't Work:

Now, the problem arises when you have multiple windows open on the desktop, they are "layered". i.e. you might have several windows open "behind" the one currently "up front". Example:

If I try to ALT+MiddleClick the "foreground window", it rarely actually resizes THAT window, and instead jumps one of the windows from behind to the front, and resizes that one instead!

STEPS TO REPRODUCE:

1) Open 3x gnome-terminal windows and say some nautilus window. Place them overtop one another. (like the above image)

2) Try to ALT+MiddleClick the foreground window.

3) Repeat this always trying to grab the foreground window.

For me, the window manager seems to bring some window from the background to the front! Desktop Recording of the Problem: [URL]
