Bug Description

Every time I click on launchpad the entire desktop gets off and restart. It's the same only with taping the alt key (but not with the atl gr key).

To launch an app in the launchpad, once the desktop has restarted (all the windows opened are restaured automatically), I can doubleclick in the app (for example firefox or any other) and the app launch, but desktop and launchpad restarts again.

I've tried to update but the message tells that the software it's updated.

The system it's 16.04.3 LTS and it was working fine until yesterday
