Hello, I am running into a issue with setting a icon for my window, I believe its because of a incompatibility with the Swing Laf library I use called DarkLaf. I am wondering if this needs to be fixed on the Compose side or the DarkLaf side. There is a exception when window tries to open, I have added it to the thread.

I will look at it later, how it can be fixed. If you want to track it, you can fill an issue

Until then you can use a workaround - set an icon directly, without passing it as a parameter

import androidx.compose.runtime.DisposableEffect
import androidx.compose.ui.window.Window
import androidx.compose.ui.window.application
import java.io.File
import javax.imageio.ImageIO

fun main() = application {
    Window(
        onCloseRequest = ::exitApplication
    ) {
        DisposableEffect(Unit) {
            window.iconImage = ImageIO.read(...)
            onDispose {  }
        }
    }
}
