All HTML5 video does not work properly when opening a new tab and visiting a website
When I am on Youtube, I go to a new tab to do something else while a video is playing in the background and I go back to Youtube, doesn't matter if the tab I previously opened is still open or closed I see this(look in the middle of the screen, it jitters):
It also happens with all other HTML5 video players on all other sites, however, it sometimes does not occur.
Please note, I am watching the video on 480p there, the higher the quality I watch the less noticeable it is, so to find this bug do the same as me.
This also happens in other browsers that use the Chromium engine.
To add to this, the problem also happens when I open a video in a new tab on the background with left control + click or middle mouse click and then either close the original page where I clicked the link or go to the video by clicking the opened tab.
The problem does not happen when I open a video in another window.
