I notice that https://w3c.github.io/mediacapture-screen-share/#dfn-display-surface says:

A single application might have several windows available to it, and those can be aggregated into a single application surface, representing all the windows available to that application and therefore presented as a single MediaStreamTrack

…that is, for what in MDN we’re here (now) describing as “all of the windows of an application combined into a single surface”, the spec calls application surface. But that said, it’s included in a bulleted list that’s prefaced with:

Collectively, these are referred to as display surfaces, of which this document defines the following types:

…so I guess from that we can assume that application surface is implicitly a subtype of display surface.


<p>There are two types of display surface. A <strong>visible display surface</strong> is a surface which is entirely visible on the screen, such as the frontmost window or tab, or the entire screen.</p>
