After upgrade to 1.0.2 (from 1.0.0) it seems that my Local stopped working (seems like the value is not changed in the child sub-tree)

public enum class ContentEmphasis { Normal, Minor, Subtle, Disabled }
public val LocalContentEmphasis: ProvidableCompositionLocal<ContentEmphasis> = compositionLocalOf { ContentEmphasis.Normal }

then using it like this

fun Foo(label: @Composable () -> Unit) {
    CompositionLocalProvider(LocalContentEmphasis provides ContentEmphasis.Minor) {
        label()
    }
}

seems that components in label doesn't have the value changed.
Did something changed? Or is my code wrong in some way?

Ok, part of this issue causing this is that I have this explicitly defined in my Theme composable. So it seems that the "redefinition" does not work.

Seems that splitting multiple CompositionLocalProviders to one per local fix this:

CompositionLocalProvider(
    LocalTextStyle provides OrbitTheme.typography.bodySmall,
    LocalContentColor provides OrbitTheme.colors.content.normal,
) {
    CompositionLocalProvider(
        LocalContentEmphasis provides if (enabled) ContentEmphasis.Minor else ContentEmphasis.Disabled,
    ) {
        description()
    }
}

Still, not able to reproduce in different project.

This is super weird and super interesting. I had problems myself with Locals today.

Here is a report. Currently it seems that behavior is changed per device. It works on some devices, it does not on others.

Would you describe your problems as similar?

[Lorenzo Benevento]

I honestly did not investigate it that deeply but it may look similar, yes. I'm going to investigate a bit and I'll tell you!

Apart downgrading and hacks in the issue, also update to 1.1.0-alpha03 fixes this. It seems that 1.0.[12] is broken.

Ok, I believe this is not connected to Compose version, more in the issue (also with another repro)
