Public bug reported: In Ubuntu 21.10 and earlier, the dock treated the edge of the screen as a hotspot for its app buttons. In 22.04, that has changed. Moving the cursor to the edge of the screen no longer triggers a hotspot on the closest app button. This reduces usability in my opinion, as switching apps via dock icons now requires more precise cursor movement. Pretty much every other control in gnome shell (activities, clock / notifications, keyboard layout select, system menu in top right) can be activated with the cursor at the edge of the screen.
This is on a machine that was just upgraded to 22.04 from 20.10. $ apt-cache policy gnome-shell-extension-ubuntu-dock gnome-shell-extension-ubuntu-dock: Installed: 72~ubuntu5 Candidate: 72~ubuntu5 Version table: *** 72~ubuntu5 500 500 http://us.archive.ubuntu.com/ubuntu jammy/main amd64 Packages 500 http://us.archive.ubuntu.com/ubuntu jammy/main i386 Packages 100 /var/lib/dpkg/status ** Affects: gnome-shell-extension-ubuntu-dock (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1970969 Title: Edge of screen is no longer a dock hotspot in 22.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell-extension-ubuntu-dock/+bug/1970969/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
