I upgraded with a dist-upgrade, zypper dup, yesterday and have the same symbol. It’s not an icon, because icons are supposed to be easily recognized even if changes are made. I assumed it was done to match the other artless symbols in the system tray. :D.
I noticed that too. It is butt ugly! I hope they come to their senses and change it back, or design a more elegant icon. For now I have removed it from the panel so I don’t have to look at it.
