At the beginning of the summer I started to have a problem with YouTube where the progress bar would not disappear in full screen. I just refreshed the page and it would go away.

Now, if I change any video settings, like the quality, it will do the same thing. I have to refresh the page again.

After a while it started to not fix after I refreshed the page.

Why is it doing this?
