XF 2.2 Navigation row colour produces a 1px line under the tab, how to remove?

As seen here, right under the tab. I am unsure how to remove this line directly under the selected tab. Thanks for any tips!

It's a dev site behind htaccess, it seems to be doing it on safari (latest version) for me anyway. I tried zooming in and it disappears, reset to normal view and it's back. It does not appear on google chrome. I see it on this site too from safari. Strange.
