This may occur on other sites, but I notice it often on YouTube when I fullscreen a video. To make it disappear, I have to mouse over a link that changes the URL in the bottom left. If a video is in fullscreen, I have to exit fullscreen to do that.
This issue still occurs in safe mode.

this seems to have been recently introduced, started seeing this about a month ago. Also not sure what triggers it exactly unfortunately :/
I’ve noticed this for about 6 months or so, particularly on full screen videos
I have this too, when I switch tabs (and back again) it’s gone.
Try scrolling up in full screen mode. On my mac, I can do that and then move the cursor over one of the other videos and then the url will go away.
Reach out to YouTube to report the issue.
