Description of problem:
Custom dnd view:

Normal view:

It seems like the background of the element is differnet. When I disable the background style it works.
I think the dnd view should behave like in a normal view.

Can you tell me the config you are using to make this background? I am seeing the same when I add a background image on both types of views

I use this configuraton for the background:

This in the config for the views:

background: var(--background-image)

This in my theme:

  background-image: "center / cover no-repeat fixed url('/hacsfiles/themes/ios-themes-custom/homekit-bg.jpg')"
  lovelace-background: var(--background-image)

Here is the image:

It seems like the grid-dnd element also has a background set but this container doesnt fill its parent view. Therefore it places a background above a background.
