Video elements' content doesn't fill all available space on some resolutions, I assume problem occurs when video element's width becomes fractional. As all available space, I mean area painted by background-color https://jsfiddle.net/uzr0wp9h/2/ Here is example of the video with red background, background is visible on the right edge of the video. Desired behavior: video content should have the same width as video element and no background should be visible Bug reproduced in Chrome too. Firefox and Edge are okay with it.
