How do I fix error popups being empty?

[Kirill Grouchnikov]

Start by showing some code behind this screen

I've also encountered this a lot for many different errors, just assumed it was some quirk with compose desktop

[Kirill Grouchnikov]

This looks like a generic error dialog shown by Swing from its default exception handler. The empty button is the clearest indication that this isn’t a compose dialog - it’s the default Metal Ocean theme

Here's an easy reproducer:

@Composable
fun App() {
    throw IllegalStateException("Some Error")
}

It’s a Swing dialog Compose is showing when (as you’ve showed) there’s an exception in a composition. But I’m getting this on

fun main() = singleWindowApplication {
    throw IllegalStateException("This should not be called")
}

Here's that exact same code on my Linux machine.

What JVM are you using?

Also what compose multiplatform version?

OpenJDK 21.0.7, Compose Multiplatform 1.7.3
