Comment(by tonyforster):

 No steps to reproduce, just patience. This will not capture in a
 screenshot, its like the flicker of a normal fluorescent light in your
 peripheral vision. I guess the screen refresh is just visible at times,
 though why you would notice it when the display is constant is a bit of a
 mystery. Maybe the brightness of pixels changes marginally during rewrite
 or maybe the processor is putting a bit of noise on the voltage rail.

 I have noticed it on the XO-1.5, (now I am looking for it) but it seems
 less often than the 1.75.

 I have no problem with closing this as not a bug, particularly as nobody
 else has noticed it. I just dont want this closed for the wrong reason.
