How to solve the problem that video doesn’t run smoothly and the problem that screen is not clear when sharing screen?

Hi guys,
Do you know the ways to solve the problem that video doesn’t run smoothly
and the problem that screen is not clear when sharing screen with jitsi meet?
When I share screen with other software such as Skype or Zoom, the video runs smoothly and the screen is clear, do you know what techniques can solve above problems?

Thanks
