List Background

Does anyone have any clue as to how to get rid of the grey background of my list? I've actually tried everything I could find online. .background(Color.clear), .backgroundStyle(.clear), init(){...}. nothing. I even tried replicating it in a new project and it didn't even show up there. Any idea as to how to get rid of this?

With SwiftUI Apple switch from UITableView to a custom implemtation based on UICollectionView. Thus all known workaround do not work anymore. Please file a Radar.
