Tab-Screensharing within chromium Browsers not working any more

[Laut Hals]

Hi guys, 

I´m teaching with BBB from my Windows 11 PC, using Brave.

Screensharing of tabs is essential for me. Since Dec 3th, it´s not working any more. It was the day, when Brave (and/or Chromium) was updated. I documented the updated version two days after:

Brave 1.85.111 (Official Build) (64-Bit)
Chromium: 143.0.7499.40

Currently, there has been new updates and I´m now on:

Brave 1.85.116 (Official Build) (64-Bit)
Chromium: 143.0.7499.110

My team-teaching mate also faces the same problem more or less since the same day. She is using Chrome on Mac.

I´m now using a portable version of Brave for Windows, which has an older build. There, it´s still working, so I guess the update causes the problem. 

Does someone know how I can use my "normal" Brave browser again? Downgrading would be an option, or waiting, until some newer builds hopefully fix the problem, I assume.

Do some of you also face this problem?

I already opened a thread on this on Brave.

Thanks for your help in advance.

All the best

Jakob

Hi, which version of BBB are you using? This issue was fixed in version 3.0.18

I have experienced similar issues with BBB while using inside my LMS.

Screen is cropped and does not show full content unless slides are set to 4:3 ratio and screen sharing 

stopped working also.

Curious as to why BBB does not have a support contact to provide guidance other than isers sharing what they discove

Our school is currently using BBB version  2.7.16

I´ll try to reach out to the tech-service team and ask them if they can update BBB. Thanks a lot for this suggestion, Miichelle!
