Narrow bar at bottom of each new page mirroring background
Sorry for the poor title, but how to better describe this bug?
See the screenshots.
The one with the white strip at the bottom is because the background color is white (empty text file). The second screenshot shows the Tor Project website in the strip at the bottom, because your website was loaded in the background with a different browser.
The strip goes away if the browser is resized.
