This bug was fixed in the package unity - 5.18.0-0ubuntu1
---------------
unity (5.18.0-0ubuntu1) precise-proposed; urgency=low
* New upstream release.
- Launcher: start the drag icon request from the original mouse-down
position. (LP: #858540)
- Ignore transient unmmaped windows on minimize/unminimize
(LP: #929712)
- Fixes alt+tab losing focus when alt+tabing to quickly due to ubus
being to slow to send a message (LP: #1035628)
- If no icon is found then use the default one. This will cause all
blank icons to be a '?' icon (LP: #886778)
- Use GMountOperation in g_volume_mount. GMountOperation provides a
mechanism for interacting with the use. (LP: #713432)
- Do not reuse the menu entries if their order changes (LP: #1062283)
- BamfLauncherIcon: ensure the icon and name values when the running
state changes. This avoids to get "?" icons. (LP: #772986)
- Use linear filtering to draw icons (when needed). (LP: #1036231)

Bug description:
[Impact]
Focus losing possibility when alt-`/alt-tab:ing.
[Test Case]
Alt+Tab doesn't lose window focus
---------------------------------
This tests ensures that a racing condition is not possible anymore when
alt+tabing.
Setup:
#. Have 2 windows of different types open. (gedit, nautilus)
Actions:
#. Press quicky Alt+Tab. (so that the switcher window is not shown)
#. Repeat 10 times.
Expected Results:
No window loses focuses at all. The panel should alway show the title of the
window.
[Regression Potential]
Application switching in general.
---
SRU TESTCASE:
1. open two terminals
2. quickly press alt-` a couple of times so that the switcher appears
What should happen:
no matter how many times you alt-` the focus should never be lost i.e. unity
panel should not look like comment#6
-----Original Report-----
Ever since upgrading to Unity 5.14.0-0ubuntu1 a few days ago, my alt+tabs
have been constantly breaking. I use alt+tab quickly, fast enough to never see
the switcher. The issue is that a good percentage of the time, the window is
brought to the front and the focus is momentarily flickered onto the desired
window but then the focus is entirely lost: Nothing is in the titlebar and any
input goes nowhere.
I don't recall any problems with the version previous to this update
pushed (5.12-0ubuntu1.1)
video demonstrating the bug:

Alt+` also loses focus regularly, even if there is only one window.
