VLC Icon in Indicator Applet Complete



When I use the Numix circle icon theme, the VLC icon in the applet doesn’t scale properly as you can see from the following picture:

It’s not until I increase the panel size up to 30/33 it scales up properly. I’m using a gtk.css config file with padding as follows:
padding: 4px 0px;

It could be fixed somewhat if I use 1 or 2 px instead of 0 but that makes the spacing among menu items of the applet much smaller and out of proportion.

Is there any workaround to this?
