Bug Description
When report was generated, the Alt+Tab task switcher was stuck. I could access all interface elements as I normally would, but the task switcher was stuck in the foreground of everything and would not hide and open the selected application window as it should.
I don't know how to reproduce the issue, but are reporting it for the record.

I can confirm that. It sometimes stuck but I also don't know how to reproduce it.
I have attempted to reproduce that. This is one way:
1. Open empathy chat window
2. Input text with *ibus* *enabled*
3. Send text by press enter
4. Using Alt + Tab when the cursor is *still* inside textbox
-> Result: Task switcher is stuck on the foreground.
Another way: Using Alt+Tab by Onboard (The default onscreen keyboard in Oneiric).
I confirmed with alt-tab through Onboard.
+ window switcher stuck when alt-tab with Onboard
Yet another way:
1. Open a terminal.
2. Run the command 'xprop'.
3. Press Alt-Tab.
4. The task switcher is stuck.

It also happened for me without onboard or xprop, just by pressing alt-tab and then doing "something" that the switcher didn't like.
Attached is the output of xininfo -root -tree when this happened.
It seems like a serious usability issue, in that youcan barely use your system once the switcher is stuck.
Raising the priority and nominating to the weekly milestone list for consideration.
+ window switcher stuck (not only, but can be triggered with )Onboard
+ window switcher stuck (not only, but can be triggered with Onboard)
This fix is in for the case other than onboard. Onboard unfortunately is a case where you can't unselect the "alt" so alt-tab thinks you are still holding the key. This is out of scope for the bug.
This bug was fixed in the package unity - 4.16.0-0ubuntu1
