can't alt-tab restore minimized uis which have an instance on another workspace

[Sebastien Bacher]

Using unity 5.4 candidate from the staging ppa:

- go on a workspace, run an application, let's say gedit
- go to an empty workspace, middle click on gedit in the launcher to open a second instance
- on the same workspace open something else, let's say nautilus
- still on the same workspace, minimize gedit
- nautilus should be focussed at this point
- try to alt-tab back to the minimized gedit without wanting for the preview to appear

-> that doesn't work, selecting gedit in alt-tab doesn't bring back the ui

I thing there are huge problems with Unity Switcher (Alt+tab) and Scale plugin (super+w) when "static Application Switcher" plugin (which is the old original compiz switcher) is set. deactivating it solves a lot of problems.

Unity --reset is re-activating this plugin.

compiz (1:0.9.7.0~bzr2995-0ubuntu5) precise;
unity (5.4.0-0ubuntu2) precise;

no change for this problem
