Well, given that `gcolor2` is open source, it does already work with Wayland if you have XDG Portal setup correctly.

And Zoom could, too, if they cared. (And by the way, I use Zoom in browser with Wayland when required by <obligation>, and it works fine.)

Once again, people miffed at Linux because closed source app developers are lazy and don't give two shits. (Which would be and often is a pain for plenty of other reasons than Wayland.)

I don't know what xdg-portal is or how to set it up. When I searched in Google, the very first link has a bad SSL certificate (which I accepted anyway, but seems very complex at first glance), the next from Reddit didn't work and said the tutorials were all out of date.

I totally agree Zoom should fix it, but they haven't yet.

I tried to install xdg-desktop-portal with ` nix-env --install xdg-desktop-portal` but running xdg-desktop-portal does not find the binary. I'm just confused what this command does anyway.

There is a lot of conversation about Zoom here: https://github.com/flathub/us.zoom.Zoom/issues/22

Apparently, there has been some recent activity via support channels. But I’d bet it’s probably not that difficult, just a matter of the team’s priorities to get to it. Then again, zoom isn’t very active or transparent in the OSS world, so it’s hard to say.

Their developers to implement some dbus protocol probably?

More accurately, the developers need to a) fix the buggy implementation of the Gnome-specific protocol they currently use, and b) switch to the standard screensharing protocol.

Zoom happily supports screen sharing on Wayland/gnome, even using the flatpak version.

Not if you use screen scaling.

For what it's worth, I do use screen scaling (in fact: different scales on different screens) and haven't had trouble with screen sharing on Zoom on Ubuntu in over a year.
