I should point out that text never really "fade away." Every text character has embedded within it a "phase angle" value which rotates through 360° with various angles representing different colors.
Some of these colors are light gray and pale white.
So I think that what you see is not the text "fading" but something corrupting the meta data telling your computer which color, hue and intensity to display certain text characters.
PS: Nothing faded out here, I merely altered the color phase angle of each line accordingly.
