This morning, I managed to trigger this bug again. I installed a new component from the Activities/Search view. The component installed without requiring any authentication, but 30 minutes later, the offending authentication dialog image appeared on the screen.
I believe there are probably two different bugs here: 1. In the ubuntu software install, there is probably a thread synchronization defect that allows software to install without authentication. 2. Separately gnome shell appears to paint widgets even though there is apparently no logic/process attached to the widget. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1824874 Title: undismissable, unclickable authentication dialog left on screen (top- left corner) after policykit authentication [pushModal: invocation of begin_modal failed] To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1824874/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
