Details

When fullscreening or unfullscreening a video (say on YouTube, or Twitter), there is often a several-second long process that looks visually pretty glitchy before the act is complete. I've filed this for Linux, but it's the same on Android and it's the same on both X11 and Wayland, for what it's worth.

Here's a video on my 40-core desktop PC with dedicated AMD graphics, running GNOME in Wayland mode: https://photos.app.goo.gl/ZLQfaHRUT9SJLHXA7

That's not great at all, and it's often much worse.

The same thing with Chrome on the same computer is much smoother and has fewer visual steps. Not really sure if this is graphics, layout, DOM or a combination of all three.
