Chromium and a strange young man instead of a button to close

Today I noticed that in the place where there should be a “close” button in the browser, there is a photo of some young man. Remove does not work in any way. In this regard, the question to all who can help: who is this, and why does he look at me?



If they change, and even blink, I will stop turning on the computer: I am not a scout, my nerves will not stand.
