A viewer has an issue with the video overlapping the chat, he linked what he is seeing http://cache.gyazo.com/76c3e8392f6572c439a1728f1604f15e.png I also have this issue but it only covers my scroll bar so I never thought anything of it. I don't know what he has, but I use Firefox and my screen resolution is set to 1366x768 (It's my laptop)
I get that as well from time to time. Refresh the page and it should be gone. It mostly happens when you drag the browser window from a big screen onto a smaller one. That's what it is for me at least.
It was just too big really, something to do with how the modules wrapping was as well.. I've reduced the size of the chat and people report a fix but now of course, people with big screens complain about the smaller size :L
Both the links under the radio chat open up the radio player for me rather than the chat, and they open it on the page rather than make a new one...
