I can verify this is true. With the Human theme the leftmost (Menu Bar) and rightmost (Notification Area, Date/Time, Indicator Area) portions of the upper panel do indeed become transparent. This also affects the Trash Icon and Window List applet on the bottom panel as well.
All of these areas become transparent when selecting the "Human" or "Human-Clearlooks" Gtk themes. The problem seems to be when you have either the "Radiance" or "Ambiance" Gtk theme selected. ** Changed in: light-themes (Ubuntu) Status: New => Confirmed -- panel transparency broken with light theme https://bugs.launchpad.net/bugs/538853 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
