[Q] Weird transition behavior & AndroidView not clipping bounds

[Jan M]

So, I am building an app that opens a CameraPreview (using this library for now https://github.com/ujizin/Camposer) .

However, it seems like the CameraPreview, for the time of transition, is not staying within it’s bounds. To illustrate the behavior I am wrapping the Preview in a BoxWithConstraints and settings the requiredSize to height/width - 100.dp (that explains the gap on the side and bottom. So like this:

BoxWithConstraints(modifier.background(Color.Red)) {

    CameraPreview(
        cameraState = cameraState,
        imageAnalyzer = imageAnalyzer,
        enableTorch = isTorchOn,
        isFocusOnTapEnabled = false,
        modifier = Modifier.requiredSize(this.maxWidth - 100.dp, this.maxHeight - 100.dp)
    ) { .... }
}

The translation used is:

val slideInHorizontallyAndFadeIn = slideInHorizontally(
    initialOffsetX = { 300 },
    animationSpec = tween(
        durationMillis = 400,
        easing = FastOutSlowInEasing
    )
) + fadeIn(animationSpec = tween(400))

Any idea what cold cause this?
