Hello everyone,

I try to show active speaker on a canvas, it works perfectly on web but on mobile it glitches. Is there any other approach to this situation?

```auto
client.on('active-speaker', (payload) => {
      setNowTalkingId(prevTalking => {
          let userId = payload[0].userId
          if (prevTalking != userId && userIdRef.current != userId && userIdRef.current != null){
              let acrossVideoCanvas = document.querySelector('#videoFrameAcross')
              try {
                  mediaStreamRef.current?.stopRenderVideo(
                      acrossVideoCanvas,
                      prevTalking,
                      undefined,
                      undefined,
                      undefined,
                      userId
                  )
                  if(client.getAllUser().filter((user) => {return user.userId === userId})[0]?.bVideoOn) {
                      mediaStreamRef.current?.renderVideo(acrossVideoCanvas, userId, 1280, 720, 0, 0, 2)
                  }
                  return userId
              } catch (error) {
                  return prevTalking
              }
          }else{
              return prevTalking
          }
      })
  })

```

Hey @uyaniksigma

Thanks for your feedback.

Are there any errors on the console when the code run on the mobile browser?

Thanks
