Code to reproduce:

import SwiftUI
import SDWebImageSwiftUI

struct ContentView: View {

    @State var someState = 1

    let imageSize = UIScreen.main.bounds.size.width - 50
    let imageURL = URL(string: "https://www.trekcast.de/wp-content/uploads/2021/02/trekcast2014-1400.png")

    var imageResizingTransformer: SDImageResizingTransformer {
        let screenScale = UIScreen.main.scale
        let size = CGSize(width: imageSize * screenScale, height: imageSize * screenScale)
        return SDImageResizingTransformer(size: size, scaleMode: .aspectFill)
    }

    let timer = Timer.publish(every: 1, on: .main, in: .common).autoconnect()

    var body: some View {
        VStack {
            WebImage(url: imageURL, context: [.imageTransformer: imageResizingTransformer])
                .resizable()
                .frame(width: imageSize, height: imageSize)
            Text("\(someState)")
        }
        .onReceive(timer) { _ in
            someState += 1
        }
    }
}

Occurred with Version SDWebImageSwiftUI 2.02 on Xcode 12.5.1 / iOS 14.5
