[Linux] Single screen selection shares all 3 monitors, squished into one unreadable window

Taylor Thurlow
Ubuntu 18.04 LTS with Gnome.
The title pretty much explains it - it squashes the contents of all 3 monitors into a single-monitor-sized picture, and that's what gets displayed to my partner. The three displays are stacked horizontally.
EDIT: I should also mention that it's not letterboxed - the aspect ratio of each monitor is not preserved - this is why it's not readable.
EDIT 2: The host OS was macOS 10.15.3.

J Sherwani (Pop Team): Thanks a lot for working of this!
It
almost
works: The mouse uses the correct coordinate system, relative to the selected monitor, and only one monitor is shared.However, no matter which one is selected, and despite the mouse using it's coordinates, the image is always streamed from the
first
monitor (the first one to be shown when running xrandr).This is the case both on Kubuntu w/ i3wm and a colleagues Linux Mint machine.
As far as I can tell, the mouse cursor tracking is correct, but there is a small bug in the monitor selection :)

Bennett Piater: Sounds like https://screen.canny.io/bugs/p/linux-with-multiple-monitors-user-sees-one-screen-but-their-clicks-interact-with — is that correct? Are you on the latest update (Version 1.0.16, pushed out 7 hours ago)?

J Sherwani (Pop Team): It's not exactly the same bug - no matter which screen we select, the viewer interacts with the correct one, but the video is from the first one.
Also, your response time is amazing!

Oh, sorry - we are both on 1.0.16.

I’ve made a new bug to track this, and have added you to it: https://screen.canny.io/bugs/p/linux-screen-share-only-shows-1st-monitor — let’s take the conversation there.

Still not working well, with Lenovo T470p and a Acer 34" wide screen. When sharing the wide screen, the image was squashed for my colleague with a MacBook Pro 13" 2018 (Mojave 10.14.6).
Then I tried to share the laptop screen, and there my colleague saw the edge of the wide screen browser window (still image was squashed). After choosing the laptop screen, I couldn't share anything else but that, even though I chose to share the wide screen, it only showed the laptop.
Also when my colleague used drawing, it was off with at least 5cm.
And yes, I updated to the latest version from snap.

Kenneth Söderlund: could you please share a screenshot of your actual setup along with what is shown in Screen? You can do this yourself by opening the meeting link in Chrome. Thanks!

J Sherwani (Pop Team): I confirm the issue is fixed for me with this release (I'm using Linux Mint 19.3)

Sorry for the delay in getting here (we were inundated after our public beta launch yesterday)! This is the top-most feature request, so we're tackling it first.

Same here. Just did a test with 2 people both on Ubuntu, one on 18.04 the other on 19.10 with multiple monitors, me with 2 as an extended desktop, the other 4 monitors as extended desktop. When screenshare activated, it correctly highlights the monitor you wish to choose, but then shares all monitors making things unreadable. When the other person changed their setup to mirror on all monitors, then their desktop was correctly shared... The audio and video was otherwise flawless.
Exciting stuff though guys. We have been battling with Google hangouts/meet with screen sharing on Linux for years, you could either share all monitors or a single window. If you guys get this right for multiple monitors where you can share just one, Screen will be our next go to.

Two monitors from Ubuntu 18.04 appears squished together on my Win10 system.

I can confirm this with Linux-to-Linux and 2 monitors.
The monitor selection works, and both partys see one monitor highlighted, but all images are squashed together in the video.
Thank you for supporting Linux this time!
