Which version of Compose do you use? This looks like nested subcomposition dispose, but it is supposed to look slightly differently on newer versions

[Jan Skrasek]

Yes, an old one. Is it supposed to get better in newer ones? 🙂
composeBom = "2023.10.01"

[shikasd]

This one is not that old, tbh
In general, onForgotten blocks are disposing launched effects / disposable effects, but I don't remember seeing nested disposal before outside of subcompose layout.

[shikasd]

I would check what this block does in debugger, maybe you get some idea of where it is coming from

[Jan Skrasek]

In other words, having fewer LaunchedEffects will reduce the time spent on their cleanup, right?

[shikasd]

That is correct, as a general rule, coroutines are not free, so fewer launches/cancels is always good
launched effects are never nested really though, so it is unlikely what you see here

[Jan Skrasek]

Thank you 🙂

Or perhaps you've mistakenly used a frequently changing state as the key for a LaunchedEffect, like this: LaunchedEffect(key = animatedState.value) { ... }.

[shikasd]

Rather than looking at launched effects, consider checking your subcompose layout usage (e.g. nested lazy or box with constraints). It looks more like that rather than something else.
