Screen sharing fails on Wayland

[GalouFR]

Steps to reproduce

When I am in a video conference and I want to share my screen this does not work, the dialog box which allows you to choose between the whole screen and a window appears but it is empty and the share button at the bottom right is grayed out when I use Wayland on the other hand it works correctly with x11 the dialog box shows my screen correctly and I can share it.

Outcome

What did you expect?

I wish to have a fix or solution to make it work natively with the default ubuntu configuration (wayland)

What happened instead?

The share button is grayed out and it is impossible to select the screen or application to share because it does not appear.

Operating system

Ubuntu 22.04 LTS

Application version

just to make sure... do you have an XDG Desktop Portal installed for your desktop env?
They are needed for securely accessing resources from outside an application sandbox.

Hi @GalouFR
it is not a requirement of the chat client... It is more of a requirement imposed by Wayland and pipewire.

In #2058, @Destinyg133 is saying that

I managed to fix it by adding these for electron config "--enable-features=WebRTCPipeWireCapturer"

"--ozone-platform-hint=auto"

You can set these flags more permanently by means of [modifying the .desktop file]of an application and adding the flags to the end of the Exec= line, or more cleanly by using the configuration files.

It didn't work for me though.
