Nathan Teodosio (nteodosio) wrote : Screen sharing fails under Wayland when switching between sharing modes

In Wayland,
open Chromium,
go to https://mozilla.github.io/webrtc-landing/gum_test.html,
Screen Capture,
click the "Window" tab of the dialog,
choose any window in the pop-up window and click "Share", but don't click the other "Share" in the transient dialog inside Chromium.

Then, change your mind,
click the "Entire screen" tab,
choose any display in the pop-up window and click "Share".

Expected
--------

The display is shared immediately.

Observed
--------

This appears in the stderr:

--->

and the display takes a considerably long time — about 10 s — to be shared, which is unnacceptable on its own, but also this time is also sufficient to lead the user to think: "it doesn't and won't work, let me just cancel this."
