I don't know how to describe this, but every time I open a video, or sometimes it's not even necessary, the operation basically "opens and closes" I say this because it doesn't technically close, but describing it in general is: I click on the page>video /open new page>operates goes to the same screen that shows when the page is reloading>returns to normal. From time to time this happens out of the blue when I haven't opened any pages or I'm just watching videos, but it's mostly when I open videos.
