> Do you have use cases where capturing a part of a screen would be best compared to say sharing a tab or a window? @youennf I think I have one such use case completely away from the initial topic of screenshots. My (and others) default behaviour when sharing an entire screen used to be to share a screen with nothing on it - take the scenario of a laptop and an external monitor; I used to use the laptop screen as a "blank canvas" I could put content on - applications of all nature. When you're sharing content in a meeting or such, its a completely fluid thing - one minute I might be sharing code, another I could be looking at some docs in a browser. I don't want to keep switching which application is shared using getDisplayMedia so I just share an entire window. The trouble is I used to use my laptop monitor because it wasn't 4k (like my external monitor) - it meant people could actually read what was being shared etc etc. Long story short, I've just changed from having one external 4k monitor to 2 and I no longer have my laptop open - so what option do I get given when wanting to do exactly what I did before? I'll show you.  This is the output of Chrome's getDisplayMedia GUM - you can see I have 3 monitors.... an ipad pro using sidecar (my temporary hack for this scenario), a vertical 4k monitor and a horizontal 4k monitor. Some others [have their own solutions](https://twitter.com/elminiero/status/1309383359936761856?s=20) like changing the resolution on their monitor to lesser so that they can share their screen and make it easily readable but that's not going to work here. I have a vertical monitor that will _never_ share well. Should I rotate it every time I want to do a screen share in a meeting and take the resolution down? No. Should I change the resolution on the primary monitor? No - because then everything else on my display would get shown to the people on the other end of the call - thats another partial reason for always using the "blank canvas" of the laptop monitor before - when you work with multiple clients - you don't want your clients seeing content from your other clients. So now, I'm lucky enough to be in this position. I've got two lovely 4k monitors infront of me and an ipad pro enabling my "hacky" solution for the moment. But for a moment don't think about the specifics, and go back to something else I just said.... I need a way to be able to share multiple applications all within one stream without showing off the content on the rest of my display - that's a perfect use case for this and if its being done to enable privacy reasons - then it should be down to the browser to do it and not be up to the application to action with cropping (ouch... cropping of real time video within javascript userland....) - for privacy reasons the browser should be the one giving over a stream only containing what the user selected when they say.... dragged an area they're OK with sharing. The way I see this working is very similar to how Quicktime does screen recording - you drag an area, everything else goes slightly darker and you're able to see exactly what has been shared with the application. So what do you think? This is definitely more than wanting to create screenshots. This is about offering flexibility. But while we're at it - with the likes of project fugu around.... don't we want web applications and the like to be just as good as say Zoom? Zoom lets me share a portion of my screen.... why shouldn't the browser? -- GitHub Notification of comment by danjenkins Please view or discuss this issue at https://github.com/w3c/mediacapture-screen-share/issues/105#issuecomment-698793665 using your GitHub account -- Sent via github-notify-ml as configured in https://github.com/w3c/github-notify-ml-config
