Describe the bug

When pushing new image from home assistant the screen gets this funny distortion shaking animation for a couple of seconds. It also takes a long time to load the image. (Image size: 121Kb)

To Reproduce

Just clicking the refresh button or switching page makes it happen.
Haos automation:

alias: Ducks → Plate2 camera image
description: Convert Frigate stream to PNG and upload to Plate2
triggers:
  - trigger: state
    entity_id: number.plate2_page_number
    to: "5"
    id: page_change
  - trigger: mqtt
    topic: hasp/plate2/state/p5b9
    payload: "{\"event\":\"down\"}"
    id: manual_refresh
conditions: []
actions:
  - action: shell_command.ducks_convert_resize
    data: {}
  - delay:
      hours: 0
      minutes: 0
      seconds: 2
      milliseconds: 0
  - action: shell_command.ducks_upload_to_plate
    data: {}
  - delay:
      hours: 0
      minutes: 0
      seconds: 1
      milliseconds: 0
  - action: openhasp.command
    data:
      entity_id: openhasp.plate2
      keyword: jsonl
      parameters: "{\"page\":5,\"id\":2,\"src\":\"L:/ducks.png\"}"
mode: single

Switchplate jsonl:

{"page":5,"id":1,"obj":"label","x":20,"y":60,"w":440,"h":35,"text":"Ducks","align":0,"text_font":28} {"page":5,"id":2,"obj":"img","x":10,"y":100,"w":460,"h":300,"src":"L:/ducks.png","auto_size":0} {"page":5,"id":9,"obj":"btn","x":410,"y":60,"w":60,"h":60,"toggle":false,"text":"\uF45@","text_font":"mdi35","align":1

"bg_color":"#3498DB","radius":10}

54 {"page":5,"id":3,"obj":"label","x":10

Expected behavior

Preferably no weird screeen distortion if possible.

It seems an issue with these baords and bad WiFi interference isolation.
I've seen people add a piece of aluminum foil to mitigate the interference from WiFi to the board.
