See dev-b2g "Proposal: an option to paint the setVisible(false)'d mozbrowser iframe with a random solid color, or chessboard pattern" We are currently throw away what's painted in the iframe if the frame is being set to not visible. Gaia devs have hard time debugging when they work on those and forget to (temporary) set a background color to those otherwise invisible frames. It would be nice if we have a pref in Gecko, when enabled, turn those iframes into a random solid color, or chessboard pattern.
It should be relatively easy to figure out which iframes are setVisible(false)'ed (for example, their docshells should have isActive == false), but I don't actually know how to paint them differently. You'll need to ask a layers/gfx person.
