I upgrade to precise a couple of days ago. I do have this bug, but I
don’t use unity! I use the static-app-switcher with compiz and gnome-
panel.

Is it a general switcher-trap and only unities switcher was fixed?

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.
