Google meet screen share is laggy

Description

Google meet screen share is laggy on both Firefox and brave. But when i use other service like jitsi meet ( jitsi.org ) it works smoothly. Also some time it fails to screenshare after accepting the prompt form the browser.

Steps to Reproduce

1. Join a google meet
2. start a screen share

Expected Behavior

A smooth almost realtime screen share

Actual Behavior

On starting screen share it was giving very low fps on the viewers side, the problem is not with the network.

Screenshots

On terminal I got the below errors
