There is a design problem on the ThinkPad x250. Touch the back of the screen when there is an image with many colors on the screen. You will see that the screen is moving(like a wave). As you open and close the computer's cover, the screen is whitening due to this design error. Especially in the middle. Due to this problem, they changed the screen under warranty.
