Display gets lighter spots after some time

Hello, i got my FP2 since August last year. After a month i noticed some lighter spots on the display, they are only to be seen with a white background (like in Settings), but then its really irritating to my eyes.
I changed the display with the help of the support and my new display shows the same behaviour after two months. The spot is on the lower half. My question: Has anyone else noticed this? I didnt find anything about this here or anywhere.
