Question

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 <https github com JetBrains compose jb issues|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 ```
