To Reproduce Steps to reproduce the behavior:

1. Checkout code from https://github.com/syru88/PopupCrash or use this snippet:

   
   @Composable
   @Preview
   fun App() {
   MaterialTheme {
       var showContent by remember { mutableStateOf(false) }
   
       if (showContent) {
           LoadingHud()
       }
   
       val coroutineScope = rememberCoroutineScope()
       Column(Modifier.fillMaxWidth(), horizontalAlignment = Alignment.CenterHorizontally) {
           Button(onClick = {
               showContent = true
               coroutineScope.launch {
                   // no crash when delay is 50ms or more
                   delay(10.milliseconds)
                   showContent = false
               }
           }) {
               Text("Click me!")
           }
       }
   }
   }

@Composable fun LoadingHud() { Popup { Box( modifier = Modifier.fillMaxSize(), contentAlignment = Alignment.Center, ) { Column( modifier = Modifier .requiredWidth(150.dp) .wrapContentHeight() .background( color = Color.Gray.copy(alpha = 0.7f), shape = RoundedCornerShape(12.dp) ) .padding(horizontal = 16.dp, vertical = 24.dp), horizontalAlignment = Alignment.CenterHorizontally, ) { CircularProgressIndicator(modifier = Modifier.size(48.dp).padding(8.dp)) Spacer(Modifier.height(8.dp)) Text("Popup") }

    }
}

}

2. Click on 'Click me'
3. See error

**Expected behavior**
No crash should happen. It's working on Android or when longer delay is used (60ms).

@MatkovIvan This problem has not been fixed in version 1.6.11. I call the Dialog to display and close it in milliseconds, but it still behaves abnormally. In addition, I have not found a way to modify the semi-transparent background of the Dialog. Can you tell me? Thank you, brother.

This problem has not been fixed in version 1.6.11.

It's not included to this version

I have not found a way to modify the semi-transparent background of the Dialog

There is no common way to do that. For Multiplatform/non-Android you can use DialogProperties.scrimColor for that

@MatkovIvan Thanks, can you tell me which version has been fixed? I encountered a similar bug in iPhone 6s and iPhone 7Plus, and I don't know how to fix it. After entering text in the input box, I keep double-clicking the input box. At this time, a copy prompt box will pop up. If I keep double-clicking the prompt box, it will keep appearing and closing. At this time, it will also crash. The exception is also the same. I feel that it is the same bug, right?

Thanks, can you tell me which version has been fixed?

It will be part of 1.7.0

I feel that it is the same bug, right?

It sounds so

@MatkovIvan There are 2 input boxes on a page. I enter text in one of them and double-click to pop up the copy prompt box. At this time, clicking the other input box will cause an abnormality. I would like to ask if there is any preventive solution at present? In addition, when is 1.7.0 expected to be released?

[liufeng382641424]

@MatkovIvan Or can I disable the copy function of the input box? Thanks bro

Sorry, it's not clear what "abnormality" is. It doesn't seem related to the topic. If you think that it's some problem that should bt fixed - please open separate issue with full description and repro

In addition, when is 1.7.0 expected to be released?

From docs: "The gap between a Compose Multiplatform release and a Jetpack Compose release is usually 1–3 months."

Or can I disable the copy function of the input box?
