Here is a little hint I picked up on the internet (Karin Prater's youtube channel) for helping when you need to see where multiple unwanted refreshes are occuring. It has helped me a lot in just a couple days off trouble shooting.

Place this in places like a row item in a list, or pretty much anywhere, just comment it out when things are working. Uncomment occasionally to make sure no extra refreshes are happening. It basically changes the background color of views every time they are redrawn. Simple and obvious!

.background(Color.random())

and place this someplace convientient.

public extension Color {

     static func random( in range: ClosedRange<Double> = 0...1, randomOpacity: Bool = false ) -> Color {
        Color(
            red: .random(in: range),
            green: .random(in: range),
            blue: .random(in: range),
            opacity: randomOpacity ? .random(in: 0...1) : 1
        )
    }
}
