* Nvidia bug 1876632 * Upstream bug https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/4477 (fixed in gnome-shell 42.rc) Maybe it's the second one because gnome-shell 42~beta-1ubuntu2 was missing that fix. The fix should already be released in gnome-shell 42.0. ** Bug watch added: gitlab.gnome.org/GNOME/gnome-shell/-/issues #4477 https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/4477 ** Changed in: gnome-shell-extension-ubuntu-dock (Ubuntu) Status: Incomplete => Fix Released ** Package changed: gnome-shell-extension-ubuntu-dock (Ubuntu) => gnome- shell (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1965123 Title: Active launchers area pixels missing To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1965123/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
