Very low fps

Describe the bug
I'm using a self hosted rustdesk-server on my Mac with docker.
But when connecting to my remote desktop I barely get 20 fps (max) and an average of 14 fps.

Why it is slow? Even is being hosted on my own private network (LAN), I also have the custom image settings at max in the client, but is still slow.

Describe the environment

• Install environment: docker
• If available, the docker-compose.yaml file:

 version: '3'

networks:
  rustdesk-net:
    external: false

  hbbs:

      - 21116:21116/udp
      - 21118:21118
    image: rustdesk/rustdesk-server:latest
    command: hbbs
    volumes:
      - ./hbbs:/root
    # network_mode: "host"
    networks:
      - rustdesk-net
    depends_on:
      - hbbr
    restart: unless-stopped

• In any case, NEVER put here the content if your id_ed25519 file

Start with the supplied docker-compose.yaml and verify the reported LAN setup, Docker image, published ports, and connection path. Reproduce the 14–20 FPS result while collecting the relevant client and server details; done should be a confirmed cause with a reproducible test or a documented explanation of the expected behavior.
