Annoying Flickering Dot on World Loading Screen

This is a very slight yet somewhat annoying bug: on the world loading screen, a small dot that looks like a particle from a dirt block appears for a fraction of a second, then disappears. It flickers like this several times. I could not get a screenshot of it, but I have supplied an image of the position of the dot.

 

Yes, I am using a Chromebook, but it runs fine.
