I have a little white mark on the lower right corner of the screen on my Xiaomi mi note

The mark appeared yesterday and i don't know how to get rid of it,you can only see it on a dark image but when the screen in white it dissapears.

It could be light bleed. Is it right at the edge of the screen?

It isn't at the edge
