I have installed NetSpeed extension on my arch-Linux. It is working properly until I uninstalled gnome-extra without affecting dependencies(-u --unneeded) package from my system. The problem is the visual bug that suddenly happened after that. The netspeed icons next to speed turn to white boxes. I checked the dependencies and packages under gnome-extra. And there's no appropriate package I could found there. I tried uninstalling and installing NetSpeed extension, but no use. I donot want to install full set of programs in gnome-extra again.
