I've got a webapp that's basically working across many browsers and other platforms, but on Safari it just stops responding with lots of JsExceptions on the console. I've basically narrowed it down to moving the mouse cursor rapidly between 2 or more Button()s. You really have to shake the cursor (if it goes big like you are trying to find it, that's the level of shaking I mean) to reproduce reliably. If I just swap out the Button with a Box(clickable {...}) { Text(...) } there is no problem! Also I've noticed that "imageviewer" and "jetsnack" don't use the standard Button (use IconButton)*.*

08/14/2025, 12:44 AMAs I said above, the JsConsole is showing tons of exceptions in WASM (can't tell where). But I've isolated this into a dirt simple 10 LOC example; its Button, not my code.
Copy code
Column {
Row(Modifier.fillMaxWidth()) {
for (i in 1..3)
{
Button(onClick = { println(i) }, modifier = Modifier.wrapContentSize(Alignment.Center)) {
Text(modifier = Modifier.padding(5.dp), text = "But $i")
}
}
}
Row(Modifier.fillMaxWidth()) {
for (i in 1..3)
{
Box(modifier = Modifier.clickable { println(i) }.background(Color.Blue).wrapContentSize(Alignment.Center)) {
Text(modifier = Modifier.padding(5.dp), text = "Box $i")
}
}
}

08/14/2025, 7:43 AM@Chrys We always try with the latest versions and in our case we even tried the latest technology preview of Safari, but our problem seems to be unrelated to this one because it is a known issue which is fixed already.
