The zoom on the Desktop does not work correctly

[GpixelProg]

Hello, I have created a test desktop project in which I added an image with Modifier.zoomable() as described in the documentation. When using the touchpad and mouse, I get the result on the video. Maybe I'm doing something wrong, or it's a bug.

OS: Mac OS Sequoia, M1

I would be grateful for an answer.

fun main() = application {
    Window(
        title = "ZoomTest",
        state = rememberWindowState(width = 800.dp, height = 600.dp),
        onCloseRequest = ::exitApplication,
    ) {
        window.minimumSize = Dimension(350, 600)

        val focusRequester = remember { FocusRequester() }
        val painter = painterResource(Res.drawable.image)

        val zoomableState = rememberZoomableState(
            zoomSpec = ZoomSpec(
            ),
        ).apply {
            setContentLocation(
                ZoomableContentLocation.scaledInsideAndCenterAligned(painter.intrinsicSize)
            )
        }

        LaunchedEffect(Unit) {
            focusRequester.requestFocus()
        }

        Image(
            modifier = Modifier
                .fillMaxSize()
                .background(Color.Yellow)
                .focusRequester(focusRequester)
                .zoomable(zoomableState),
            painter = painter,
            contentDescription = null,
            contentScale = ContentScale.Inside,
            alignment = Alignment.Center,
        )
    }
}

This is possibly due to https://youtrack.jetbrains.com/issue/CMP-2209.

Could you place a debugger breakpoint here to see what values of zoomChange you're seeing from your touchpad?

With a slight movement on the touchpad, the value and zoom reaches 1, and then gradually decreases on its own

When zooming out on the touchpad

Yeah that doesn't look good. I might have to disable pinch to zoom on desktop until the issue is resolved.
