Wayland doesn’t support full-screen sharing, for example in Google Meet (aka Hangouts). Hopefully this is fixed soon (via dmabuf-export, mentioned in the article) but until then (and for the past couple years) it’s a major hassle for a lot of people who had Wayland forced onto them by their desktop environment. Even if this isn’t Wayland’s fault they would be wise to assist with a fix soon.
