1631200 - Cursor is not shown for getDisplayMedia screen recordings

Status: RESOLVED WORKSFORME

(Core :: WebRTC: Audio/Video, defect)

Description

[Tobias]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:75.0) Gecko/20100101 Firefox/75.0

Steps to reproduce:

Screen recordings with getDisplayMedia never show the cursor, this makes screen sharing very strange e.g. when you want to demonstrate something in a video conference.

Steps to reproduce:

• Open https://www.webrtc-experiment.com/RecordRTC/
• Start Screen recording

Actual results:

Look at the screen recording below and search for your cursor, there is none

Expected results:

I expected the screen recording to show the cursor.

If you compare the behaviour of Firefox with all other browsers, you will notice that every other browser displays the cursor:

• Safari: show cursor
• Chrome: shows cursor
• Opera: shows cursor
• Edge (Chromium): shows cursor
• Edge (EdgeHTML): shows cursor

Firefox should also show the cursor by default or at least implement MediaTrackConstraints.cursor to let the application determine the desired display state of the cursor.

I forgot to mention that the wrong behaviour only occurs on Windows and MacOS. Linux is showing the cursor except for some buggy versions (#1625694).

Bugbug thinks this bug should belong to this component, but please revert this change in case of error.

Tobias, thanks for filing this bug. Can you try to reproduce this using Firefox Nightly? I tried to reproduce this using Nightly on Windows 10 and I could see my cursor.

On Firefox Nightly the cursor is displayed.

Ok, seeing as this is fixed in NIghtly, I am going to close this bug for now.
