Window focus behavior after alt-tabbing erratic after recent upgrade

[Daniel Manrique]

After a recent (~1-2 weeks) update of Unity, window focusing behavior after alt-tabbing has been somewhat erratic. I often switch between two windows, doing a quick alt-tab press, expecting the new window to both be raised and focused. However, a lot of the time, the window is not focused (indeed, nothing is; I tested this by having only two windows open and they are both greyed as inactive, so I really don't know where my keypresses are going).

 This is annoying and breaks my workflow because I have to either slowly alt-tab ensuring that the desired window is focused, then let go, or just click on it with the mouse.

Steps to reproduce:
- Close all applications
- Open Firefox
- Open gnome-terminal
- Quickly alt-tab to go back to Firefox
- Quickly alt-tab to alternate between the two windows

Expected results:
- The inactive window is raised and focused when alt-tabbing.

Actual results:
- Sometimes the window is raised but not focused.

Here's a screencast video showing the erratic behavior, I loaded screenkey so you can see what I'm actually pressing. Note how sometimes it switches to Firefox or the terminal, it grabs focus for an instant, then loses it.

that's one of the regressions that came in through our last SRU of Unity, I for example am not able to reproduce the issue. Once we have this one easily reproducible we'll get it fixed :/ (I am going to login to 12.04 and see if i can reproduce it without steps.)

Anyways, its duplicate of bug 1035628
