Public bug reported: This is seen both in Youtube and also other web-based videos as well as when videos are viewed using the local video player application.
When a video is set to be viewed in fullscreen, the video flickers and continually resizes itself. Hardware: Two displays, with one set to scale at 200% (4k display resolution), the other set to 100% scale at 1080p.
