Low image quality of picture_elements on IPAD

Hello,

I created my first floorplan layout and it works very nice :blush:.

On a desktop browser it looks like that:

Calling the same page on my IPAD, the picture has a very low quality:

Relevant code for the view:

  • panel: true
    cards:
    • image: /local/wohnung.png
      type: picture-elements
      elements:
      • entity: light.buro

Do you know how I can improve the picture quality on the IPAD?
