I made a drawing of the K-x focus screen in observation of the off-center focus ring issue mentioned in this thread:

From the drawing we can see the K-x focus screen has a wider edge at the upper side (which will be covered by the metal clip). The center focus point is located at the center of the shaded area and thus should be a little bit below the center of the whole screen.
As a comparison, the Travor screen has the split-image circle exactly at the center of the whole screen, it will appear off center when used on K-x.
