You're right, I can reproduce it. Not sure why Jitsi asks for the permissions twice. For instance BlueJeans or (webrtc test page) ask only once. I expect Jitsi creates some screen preview or so.

Marking confirmed based on Comment 2. Thank you for filing the bug!

Severity: -- → S3
Ever confirmed: true

Today I tested the behavior on the same system in a GNOME on Xorg session. I noticed that the behavior quite differs from the behavior on Wayland. In Xorg, you get a small preview of the window that you are going to share in the dropdown window when you select a specific window to share. Also, you do not have to provide permission twice.

It's because any access to screen sharing API needs permission from user on Wayland. Xorg does not need that, you can do anything you want on Xorg, the permission dialog you see on Xorg is just Firefox window, not a system one.

Priority: -- → P3

I noticed that I only have to provide the sharing permission once nowadays.
Using: 88.0.1 (64-bit) on Fedora GNOME Wayland.
