My system is Ubuntu 17.04 (updated not clean install) The problem occurs after a few hours of work. Steps to reproduce: 1. Keep working on the system for some hours 2. Press the Left Win key to get into search mode What happens then: An overview of windows will be displayed. The UI will freeze or become unresponsive. Mouse pointed can be moved around but clicking on any window thumbnail does not give the focus to it Switch to a shell using Ctrl+Alt+F1. Run top. gnome-shell is at the top with 100% CPU usage. I tried disabling some extensions to see if these cause the problem. I also tried changing the gnome-shell theme to default but no impact. Problem remains. If someone could point me to what more information needs to be gathered, I will be happy to provide it.
