Installing apps with software center brakes unity

I have received today the upgrade to the latest Unity (5.10) and wanted to see how the animation of the apps icons going to the launcher would look like.
Unfortunately, I didn't get to see it since the launcher froze, and right after that the whole desktop was rendered unusable. I couldn't do anything to unlock the situation, but press alt+F2 and reboot the PC.
