Screen sharing not working

[adewaleafolabi]

I am nable to share my screen. When I click on the button during a huddle, it does nothing. Also when I try to make a recording and share my screen I see the error

Can’t share your screen
Check your system preferences to make sure your browser has screen recording permission, and try again.

Uhmm maybe is an issue with electron permissions. I will try to check it.

I also think it's a permission issue. I tried downloading a file from within slack and got the notice Please allow pop-ups in your browser. You can [contact Slack](http://my.slack.com/help/requests/new) if you need help.

Could you try the fix and let me know if it works for you @adewaleafolabi

I tried it and:

• had to merge main before being able to start a huddle
• in principle it worked, but the window to select what to share is a bit shaky

Screencast.From.2026-08-25.09-49-03.mp4

• clicked on share screen in the huddle
• clicked on 'window' in the 'share screen' window
• the 'share screen' window was replaced by the black one without me clicking anywhere. plus as you can see the window disappears and reappears in quick succession multiple times.

Also got this error at one point and screen sharing stopped working completely:

[200352:0825/094827.122734:ERROR:third_party/webrtc/pc/rtp_sender.cc:594] Failed to set parameters since getParameters() has never been called on this sender (INVALID_STATE)

@langalex Thanks for testing this! Very useful info. Will get back to debug this.
