[Bug 1215630] Re: Hover on alt-tab easily bumped

 

Right, I've seen the problem as well... Soo a couple possible solutions:

1) Don't count small differences in mouse movement. ie. if the mouse only changed 1-2 pixels don't select the icon.
2) Don't have the mouse change the selection of the icon until it is clicked.

Adding design to weigh in.

Title:
  Hover on alt-tab easily bumped

Status in Ayatana Design:
  New
Status in Unity:

Status in “unity” package in Ubuntu:

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.
