title: On F11/Fullscreen mode YouTube IFrame zooms in really far, as a result making the video quality worse
body: <p>I used the same code as this website called <a href="https://virtualvacation.us/guess" rel="nofollow noreferrer">Virtual Vacation</a>
  so as a result they have the same issue as me. I'm thinking of reaching out to them and notifying of this but I can't figure out any way to fix it..</p>
  <p><strong>Specifically on WINDOWS 10,</strong> When you load a video, and then go into F11/Fullscreen mode, the video zooms in like 20-30%. It works on other OS like MacOS and ChromeOS, but on Windows it does that.. Here is the source code: <a href="http://view-source:https://virtualvacation.us/guess" rel="nofollow noreferrer">SC</a></p>
  <p>I have included a video with all the necessary needed like browsers, latest updates, and the steps I took to replicate the issue.</p>
  <p>Please take a look at the video: <a href="https://vimeo.com/user125246603/review/469168513/fb818b5c25" rel="nofollow noreferrer">here</a>.. it displays all the problems.</p>
  <p><strong>End question:</strong> Explanation or code example to prevent the zooming in on F11.</p>
