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

 

Public bug reported:

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.
