[Bug 1447372] [NEW] Launching an application by clicking in dash results is artificially slowed down (by 500ms)

 

Public bug reported:

As per the smart-scopes work and per the fix for lp:1189088, it has been
introduced a regression that caused unity to wait 500ms after the user a
clicked over an application icon before activating it.

Basically unity waits for a possible double click on every dash icon,
and this slows down the activation of application icons using the mouse.

1) Press Super+A
2) Click over an application icon to launch it

Expected result:
3) The dash closes immediately and the app is launched

Actual result:
3) The dash is kept open for 500ms (or slightly more) and finally it launches the application

This makes the unity dash look slower in launching an app.
