I have a theory that the defective screens lose the static charge that holds the ink particles because of the UV radiation. Window glass blocks most of the UV wavelengths.

It happened on my PB301+ when I was reading in my car, direct sunlight through my windshield.
My Cybook (EB100) doesn't have the problem but the PB (EB600) does. I was recently on vacation and reading in the sun and that's when I noticed it. I agree it's not heat related. I held my hand in front of the screen when I turned the page and after you could see the fading between my fingers. I ended up just flipping the screen when I turned the page and then flipping it back and it was fine, but it was annoying.
