Maybe it's not fading. It looks like all words were imputed as bold except for the six I put red markings under. Either that or all of the words were standard black except for six that were slightly less black (more gray perhaps). I think others see what I see. If you are having trouble seeing it, your vision might not be as sensitive as ours. I mean no disrespect. My wife and children, for example, have much more sensitive vision than I do.
