Multi touch tap events failing on desktop

[EricWarburton]

Describe the bug When tapping multiple times on the same button/card quickly the final touch event doesn't finish.

Affected platforms

• Desktop (Windows)

Versions

• Kotlin version*: 1.9.23
• Compose Multiplatform version*: 1.6.1
• OS version(s)*: Windows 11
• OS architecture: x64
• Device (model or simulator for iOS issues): reproduced on elo touch monitor and acer touch monitor
• JDK (for desktop issues): reproduced on both 21 and 11

To Reproduce Steps and/or the code snippet to reproduce the behavior: (Note: Click works as expected) Double tap a button, if you have a counter tied to the button the counter will move up by one. You should notice the button will remain highlighted. From there there are a couple scenarios.

• 3rd tap on the same button => counter will jump to 3
• 3rd tap anywhere else => counter will remain on 1
• Move mouse at all => counter moves to 2

@Composable @Preview fun App() { MaterialTheme { var counter1 by remember { mutableStateOf(0) } var counter2 by remember { mutableStateOf(0) } var counter3 by remember { mutableStateOf(0) }

    Column(
        verticalArrangement = Arrangement.Center,
        horizontalAlignment = Alignment.CenterHorizontally,
        modifier = Modifier.fillMaxSize()
    ) {
        Row(
            horizontalArrangement = Arrangement.Center
        ) {
            ButtonWithCounter("Button 1", mutableStateOf(counter1)) { counter1++ }
            ButtonWithCounter("Button 2", mutableStateOf(counter2)) { counter2++ }
            ButtonWithCounter("Button 3", mutableStateOf(counter3)) { counter3++ }
        }
        Spacer(Modifier.height(16.dp))
        Row(
            horizontalArrangement = Arrangement.Center
        ) {
            Button(onClick = {
                counter1 = 0
                counter2 = 0
                counter3 = 0
            }) { Text(text = "Clear Values") }
        }
    }
}

}

@Composable fun ButtonWithCounter(buttonText: String, counter: MutableState<Int>, onClick: () -> Unit) { Column( horizontalAlignment = Alignment.CenterHorizontally, modifier = Modifier.padding(8.dp) ) { Button(onClick = onClick) { Text(buttonText) } Text(text = "Counter: ${counter.value}") } } `

Expected behavior I expect the button to fire the event when tapped, even if tapped over and over.

@Schahen This looks like wrong usage of states. Can you check, please?
