Removing white margin on picture entity card

Configuration Frontend
1

I am using a custom: layout card to display two camera feeds

I want the picture element cards to be full width with no margins

Here is my config:

views:
  - title: Front Door
    path: front-door
    cards:
      - type: custom:layout-card
        layout_type: custom:vertical-layout
        cards:
          - type: picture-entity
            show_state: true
            show_name: true
            camera_view: live
            entity: camera.front_door_high_resolution_channel
          - type: picture-entity
            show_state: true
            show_name: true
            camera_view: live
            entity: camera.front_door_package_camera
        aspect_ratio: 100%
        layout:
          width: 1100
          max_cols: 1

On normal desktop browser it looks fine

On an Amazon Fire tablet, the top card has a white margin on each side of the video frame whilst the bottom card has no such margin

How can I remove the white margins in the top image?

Title of the issue is confusing - this is a picture-entity card, not picture-elements.

Sorry, corrected…
