Why are the control points/inner lines on the inside of cup leaking out when I zoom out? Zoomed out view: https://i.postimg.cc/9fzndvY0/image.png

When i zoom in: https://i.postimg.cc/3JHHFJqq/image.png

Blender file (the cup is on layer 2) : https://www95.zippyshare.com/v/2nyeVtve/file.html

Pretty sure I am doing something wrong here, I just don't know what it  is.

Could some help me identify it?
Set the clip end distance to a smaller value (it's in the view tab,
  press N if you can't find it)


Thanks @sacrish
