Thanks for the tip! I made new tests today and noticed that while keeping the gnome extensions off, gnome-shell stabilizes completely. I think the crash was being caused by one of the extensions or the combination of them.
At the moment I'm enjoying the new ubuntu-session interface (with the gnome-shell) and I'm reviewing the need for extensions that I had installed more by inertia than by necessity. I think I can consider this Bug as solved. Thank you very much for your attention! ** Changed in: gnome-shell (Ubuntu) Status: Incomplete => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1716456 Title: crash on click Activities when app is running To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1716456/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
