GBI on stream text - usability/legibility

Hi

When the background is white on a stream the overlay text (such as "Next Poll", "Now Playing") disappears. I wondered if a black/white text toggle would be easy to implement, I put this to chat and a suggestion came up about a black text border, which sounds like it could work although it may have an impact on font size/screen size combos. It's mostly a bother on puzzle games where the background is static.

Any thoughts?

Thanks

@mekon: does it happen if you use a different browser?
