I can say with reasonable confidence that this bug is introduced by gnome-shell-extension-ubuntu-dock_64ubuntu7_all.deb. I downgraded by downloading gnome-shell-extension-ubuntu-dock_64ubuntu6_all.deb from https://launchpad.net/~ci-train-ppa- service/+archive/ubuntu/3701.1-deletedppa/+build/16616785 and installing with dpkg. No dependency issues or conflicts were identified and the package installed without issue. I restarted my test system and the problem appears fixed.
I'll report back if this is a red herring, but I thought I should report as soon as possible so that other's might benefit. -- 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
