So if it can happen with certain types of glass why rule out that it can happen for an E-ink device?

I've actually see it happen with my (brand new) car about 15 years ago. It didn't had a layered glass windshield but a hardened one. It was parked and nothing was in the neighbourhood. I was looking at it when the windshield suddenly started to crack. It turned to 'milk' in about one minute.

The garage told me it probably was thermal stress. Later I realized that was probably correct. It happened on a hot day and one side of the car was in the sun, the other side in the shade.
