Thanks Daniel. night-light-slider.ti...@linux.com was actually uninstalled, but apparently you have to disable an extension before uninstalling it before it is removed from org.gnome.shell.enabled- extensions. In any case, it is fully removed and deactivated now.
I just noticed that you requested a reboot instead of log-out & log-in. Please let me know if you need logs collected again. You can see the GNOME shell restarted in ShellJournal.txt: [ 1066.154592] 3700X gnome-shell[13280]: GNOME Shell started at Fri Dec 06 2019 09:45:12 GMT-0800 (PST) . I made sure to reproduce the issue several times before collecting logs. -- 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/1852634 Title: Long delay before modal dialogs show To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1852634/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
