Able to repro on API 34, Compose ToT. I shortened the repro, see here.

Sean, could you take a peek at this? It seems like there may be a disconnect between the font changing and then not picking up the correct weight. That or something is off with the way the font is created here, but I'm not certain.

Forgot one part of the repro, you will need the font resources from the app to be present

Clearly caching bug, minimal repro:

private val fontWeights = listOf(100, 200, 300, 400)
private val fonts = listOf(
    "Azeret" to R.font.azeret_mono,
    "Roboto Mono" to R.font.roboto_mono,
)
@OptIn(ExperimentalTextApi::class)
private val fontFamilies = fonts.map { (_, resId) ->
    FontFamily(
        fontWeights.map { weight ->
            Font(
                resId = resId,
                weight = FontWeight(weight),
                variationSettings = FontVariation.Settings(FontVariation.weight(weight))
            )
        }
    )
}

@Composable
fun Demo() {
    Column {
        FullListRepro()
//        FullListOK()
    }
}

@Composable
fun FullListRepro() {
    Column {
        fontWeights.forEach { weight ->
            fonts.forEachIndexed { i, (familyName, _) ->
                val fontFamily = fontFamilies[i]
                val style = TextStyle(
                    fontFamily = fontFamily,
                    fontWeight = FontWeight(weight),
                    fontSize = 40.sp
                )
                BasicText("$weight $familyName", style=style)
            }
        }
    }
}

@Composable
fun FullListOK() {
    Column {
        fonts.forEachIndexed { i, (familyName, _) ->
            fontWeights.forEach { weight ->
                val fontFamily = fontFamilies[i]
                val style = TextStyle(
                    fontFamily = fontFamily,
                    fontWeight = FontWeight(weight),
                    fontSize = 40.sp
                )
                BasicText("$weight $familyName", style=style)
            }
        }
    }
}

OK composable is fine, but if you switch the order you see the incorrect behavior coming from resource font loading.
