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

#1560 has the same issue

Try to also open this one Upstream in the Hyprland Repo.

Try to run resetxdgportal.sh ?

Check if it improves anything. Screen sharing is a bit buggy on Hyprland.

https://wiki.hyprland.org/Useful-Utilities/Screen-Sharing/

This should help

I have gone thought these disscusions.Solutions given here discusses about if the screenshare is not woking completely.
But here the screenshare is working smoothly with other services(jitsi) but not working in google meet and is laggy.

I tried screensharing on this with thorium with wayland enabled and it works smoothly but on meet its lags like hell and is only 1-2 fps at max

https://www.webrtc-experiment.com/Pluginfree-Screen-Sharing/

a last resort solution that works for meet is using a virtual camera to screenshare through obs it works and is better than native meet sharing

Did anyone figure out a fix or a solution?

Make sure your screensharing app is on wayland
