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.
v117.0 (64-bit)
Windows 11 v22H2 22621.2134
I have this too, when I switch tabs (and back again) it’s gone.
I’ve noticed this for about 6 months or so, particularly on full screen videos
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.
this seems to have been recently introduced, started seeing this about a month ago. Also not sure what triggers it exactly unfortunately :/
Reach out to YouTube to report the issue.
