i'll try it again sometime soon.
i would guess it's not a matter of a certain batch of screens, but rather it only works under certain conditions.
It might be that when in direct sunlight the screen does get very warm and cools down within a second of being shaded.
It was a very warm day with the sun feeling warm on your skin, so, now that i think about it more.. it must be a heat thing. the fact that the screen refresh slows down in the cold is very telling too.
Next time i'm outside in the sun i'll try again and take a photo of it if it happens.
