I'm afraid the issue hasn't been resolved. The previous comment was a false positive.
The issue seemed to be resolved because of the bug in gnome-panel, that made the panel bigger than usual (24px), with the latest gnome-panel update, the panel is back to normal size, but the issue with the icon is evident again. The bug should be reopened. -- g-p-m panel icon doesn't scale correctly https://launchpad.net/bugs/86444 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
