Window not transparent

[smallshen]

import androidx.compose.desktop.ComposeWindow
import androidx.compose.ui.ExperimentalComposeUiApi
import java.awt.*
import javax.swing.SwingUtilities


@OptIn(ExperimentalComposeUiApi::class)
fun main() = SwingUtilities.invokeLater {
    ComposeWindow().apply {
        isUndecorated = true
        background = Color(0, 0, 0, 1)
        size = Dimension(300, 300)
        isVisible = true
    }
}

The window is white instead of transparent.

Unfortunately, we do not support transparent window on all platforms at the moment.

[smallshen]

are there any plans for the desktop platform? transparent window in UI design is popular, like blur (compose doesn't support that too I think)

[olonho]

No immediate plans for that, but we consider external contributions.
