--- Comment #4 from mdrRE rarymet <to2wodx_ at smuggroup.com> ---
Students and teachers often find that the content of some math formulas
disappear while writing at other location. The vanishing equation phenomenon is
a result of an optical illusion called Troxler fading, which makes stationary

fade or disappear when they are not in focus. If you blink your eyes rapidly,
then stare at something that is not moving for 10 seconds, you will see what we
mean by "fade". This effect can be seen with text too.
