I can reliably reproduce this issue by clicking either Activities on the top bar, or by clicking "Show Applications" on the dock.
With the latter, the Applications Search dialogue comes up, but no icons are shown for recent applications. All applications are shown as expected. Once the Search dialogue is displayed, I cannot close it. I can launch a program from the All page, and the application starts, but I cannot interact with it. If I switch into a console and kill the application, the search dialogue is still present. Like with other users, once the bug is triggered I cannot interact with anything on the screen except for items on the top bar situated on the right side of the screen (including the date and time at the center). To work around I have to switch to a console (Ctrl-Alt-F3), and 'pkill -9 gnome-shell', followed by 'DISPLAY=":0" gnome-shell'. I can then switch back to the graphical interface with Ctrl-Alt-F2. This *usually* works for me, but of course YMMV. I only noticed this bug when I upgraded my main machine today. I have another similar system which I updated a few weeks ago. In using that I experienced none of these issues. That system was updated today and it now shows the same behaviour, so whatever the bug is, it was introduced very recently. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1181666 Title: gnome-shell randomly blocks mouse clicks from working in app windows To manage notifications about this bug go to: https://bugs.launchpad.net/gnome-shell/+bug/1181666/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
