Anyone else see this strange line above the News Feed?

Hello,

This is a strange issue. Not major, but still an issue to track down a solution.

I keep seeing this line above the news feed. Not sure what caused it. It's a cosmetic issue, but there must be a way to fix it.

See image for more on where the line is. Any suggestions appreciated. I might have to check with RocketTheme as I am using a RT template.

Thanks
