What is the x coordinate on the left?
If you look at it, it will be there, but if you click on it, it will disappear and then reappear.
What is this?

I would appreciate it if you could tell me how to turn this off.
Today is Chuseok in Korea. It is also called Hangawi in pure Korean.
Good luck to everyone. ^^

Thank you again today.
