[Bug 1399740] Re: Unity: workspace switcher blocks the session

 

*** This bug is a duplicate of bug 1302883 ***

I know how to reproduce it:

1. Open three different application, i.e. Terminal, Firefox, Package Manager.
2. Launch Workspace Switcher.
3. Move one application down.
4. Move another application right.
5. Continue arranging applications around the workspaces.

In less than 10 seconds everything freezes.

Title:
  Unity: workspace switcher blocks the session

Status in compiz package in Ubuntu:
  Confirmed

Bug description:
  This annoying bug happened twice during one week. Cannot reproduce
  this this intentionally though. When I click workspace switcher button
  and try to move a window from one workspace to another, everything
  freezes, except mouse pointer. I can move the pointer, but cannot do
  anything else, so I have to do  ctrl+alt+f2 + reboot. For me it is a
  huge issue.
