White horizontal line fullscreen mode Youtube

Hello!

I am experiencing a white bottom line going horizontal and a small one going vertically when I'm using full screen mode for Youtube. It almost looks like it's a polaroid picture. I have tried closing the program and tab, but nothing seems to work. However it's just on Safari and not Chrome. I put a picture to show. Hope someone out there can help me:)

MacBook Air (2018 or later)

Youtube videos in Safari are cropped in full screen Youtube videos Safari are cropped in full screen. This does not happen e.g. in Firefox I'm not a 100% sure, but it seems that this issue started when I recently updated to Version 12.3.1 (21E258) Here's a screenshot of the video not in full screen mode (the elbow on the right is in the frame): And here's a screenshot of the same scene in full screen (the elbow on the right is not fully in the frame):

YouTube screen problem on Safari When I go to YouTube on a new window, everything is fine. I select a video, hit full screen, video plays, & everything is all good. When I revert video back to normal size, that's where the problems arise. One, the entire page is shifted to the left. Two, and more annoyingly, any videos selected at this point, for some reason, no longer fit in the video screen. All of the screen control button on the bottom right, including the button for full-screen mode, are no longer fit on the video screen. Refreshing the page doesn't fix the problem. The only way to fix it is to close the window and reopen YouTube in a new window. This issue does not happen when I use Firefox or Chrome. Let me know if there is a way to fix the issue.
