What is happening at the middle top of my lens? Is it a flare? Condensation?

This is a Tokina 11-16mm Canon EFS lens. The camera is at 11mm. When I zoom into 16mm, the anomaly seems to disappear. The anomaly happens at 0s, 11s and 17s: https://www.youtube.com/watch?v=g5zdJIt8Iok

Do you guys know what it is? Do you think it's a faulty lens? Or is it common for such a lens?
