Title:
  [Alt-Tab] Hover on alt-tab easily bumped

Status in Ayatana Design:
  Fix Committed
Status in Unity:
  In Progress
Status in “unity” package in Ubuntu:
  In Progress

Bug description:
  At some point the alt-tab application switcher seems to have gained
  support for mouse hover. This means if you have the mouse in the
  middle of the screen and then bump it while doing an alt-tab you can
  easily select the wrong application.

  To reproduce:
  1. hold alt down
  2. press tab
  3. Move mouse to the left of the switcher on the edge of an application icon
  4. Press tab a few times
  5. Move the mouse a little bit across between two icons

  Expected result:
  The selected icon doesn't change
  Observed result:
  The icon under the mouse is selected

  This is particularly bad when the icons concertina under the mouse.
  Then basically any mouse movement will un-concertina them and select
  the wrong icon.

  -----------------------------------
  Desired resolution:

  - when the alt-tab mode is entered, the pointer should be desensitised so that is no action is taken until the pointer has moved more than a certain distance in any direction 
  - To start with try using a value that nothing happens until the pointer moves more than 3 pixels in any direction. Then see how this feels, and adjust this value as appropriate to get the best feel.
