I recently switched to Linux. First I tried Pop_OS, and am now on Nobara. On both systems I have this issue, that when I open a YouTube video in a new tab, and immediately start fullscreen, it doesn’t properly do it.

As you probably know, YouTube videos start playing before the whole page has finished loading. There are some placeholders for the title and description etc, but the actual text is still loading despite the video already playing. If I enter fullscreen during this moment, the browser enters full screen mode, but not the video/website.

What I remember happening on windows is that when the page finished loading, the video would enter proper fullscreen mode. Now, on Linux, that doesn’t seem to work and the website just gets displayed regularly with the browser now in fullscreen mode.

Any ideas on what could cause this or how to troubleshoot this?
