This is with a 1.3b build, gtk2 and xft. Lots of people are reporting that the page above is corrupted after it's finished loading and when you drag a window over the top of it. I'm guessing this is a problem in gfx or in the image loader somewhere due to the way that it looks, but it's just a guess.
this occurs with the default (gtk1, no xft) builds back to at least 1.0 release. to reproduce reliably, the image needs to be reloaded from the net. viewing the image locally seems to work fine, as does viewing from the cache (sometimes) after exiting and restarting Mozilla. also, the corruption only occurs only occurs after the image has been downloaded.
another way to reproduce: load the image, select it. (e.g. by hitting Ctrl+A)
Component: Image: Painting → Image: Painting
