This also brings back dialog content size animations issues :( But on all devices this time.

See attached video

Repro:

Dialog(
                    onDismissRequest = {
                        if (dialogState.canDismiss.value) {
                            dialogNavigator.hide()
                        }
                    },
                    properties = properties,
                    content = {
                        Surface(
                            modifier = modifier
                                .safeContentPadding()
                                .fillMaxWidth(0.8f)
                                .animateContentSize(),
                            shape = shape,
                            color = backgroundColor,
                            contentColor = contentColor,
                        ) {
                            .....A composable that change it's size
                        }
                    },
                )

Can you give a fuller example for the animateContentSize() problem?

It does that for all the cases where the content change.

properties = DialogProperties(usePlatformDefaultWidth = false)

var show by remember { mutableStateOf(false) }

LaunchedEffect(Unit)  {
 delay(1000)
 show = true
}

Column {
  Text("X")
if (show) {
   Text"Y) 
}

}

Edit: This was a well known long time issue when not using usePlatformDefaultWidth = false so we were forced to workaround with that. Now even with it it trigger that. (Depending on the phone, it's either super slow, or laggy and jumping).

I am seeing a problem with decorFitsSystemWindows = false where it continues to invalidate the layout even after the animation completes. I don't think that's the problem you're worried about, though.

If I understand correctly, the problem you're seeing is something about it being laggy? And it didn't happen in the previous version, right?

That problem is likely due to the Window resizing on every frame, which is more expensive than the window content resizing on every frame. In a previous iteration, the window size was full screen and the content resized itself. You can resolve this yourself by doing this:

                Surface(
                    modifier = Modifier.safeContentPadding()
                        .fillMaxSize()
                        .wrapContentHeight()
                        .fillMaxWidth(0.8f)
                        .animateContentSize(),
...

I'll see if I can fix the problem with decorFitsSystemWindows = false invalidating layout continuously.

There's 2 very different issue here. The main very blocking is the Samsung dialogs from a bottomsheet/popup being at the bottom and under the navigation bar. Samsung is a very large percent of users. And a full rewrite of all M3 AlerDialog to something else to workaround is a pain as most M3 things are private / internal.

The second issue is about the huge lag. It was present since a very long time with usePlatformDefaultWidth = true but not with usePlatformDefaultWidth = false now it's always present.

AFAIR previously all the workaround based on .fillMaxSize() had issues with the dialog scrim, but I'll try again if there's a fix for the Samsung devices.
