can i come back to what was asked previously:
"The latest development version of compose (1.6.0-dev1383) has completely broken my layouts. The default line spacing of multiline text has been drastically increased. Is this by design or is this a bug?"
now i am obviously using 1.6.0-rc02 instead of 1.6.0-dev1383

i have read the thread and also https://github.com/JetBrains/compose-multiplatform-core/pull/996/files
but i still do NOT understand what exactly do i have to change in my app to make things work again?
the lineheight seems to be totally broken. i dont understand how to fix it. can you please help with more details/examples?

[Zoff]

i have a slider to change font size and this happens now:

[Zoff]

first lineheight size is too large then lineheight is too small

[Zoff]

Text(
    text = message.text,
    style = MaterialTheme.typography.body1.copy(
        fontSize = ((msg_fontsize * ui_scale).toDouble()).sp,
        letterSpacing = 0.sp
    )
)

Is it reproduced on 1.6.0-rc02 ?

[Dima Avdeev]

1.6.0-dev1383 - it is very old version at this moment

[Zoff]

yes. the screenshots and code sample is happening with 1.6.0-rc02

Status: Won't Fix (Intended Behavior)

The release notes documentation has been edited to clarify this change in behavior for line height.

To support non-standard text sizes, we encourage users to follow the Material design system and use a different type scale rather than changing the font size directly. Alternatively, users can overwrite the line height like so: style = LocalTextStyle.current.copy(lineHeight = TextUnit.Unspecified), or create a custom Typography entirely.

To make fontSize control lineHeight you need to provide (override) LocalTextStyle with lineHeight = TextUnit.Unspecified

[Ivan Matkov]

Basically now MaterialTheme specifies lineHeight explicitly by default, so changing only fontSize doesn't work inside it

[Zoff]

ok thanks. that seems to work

Is there any reason not to do this at the theme level rather than each Text?

@Composable
fun AppTheme(content: @Composable () -> Unit) {
    MaterialTheme(colors = ...) {
        CompositionLocalProvider(
            LocalTextStyle provides LocalTextStyle.current.copy(lineHeight = TextUnit.Unspecified),
            content = content,
        )
    }
}

My message above suggests exactly this

To make fontSize control lineHeight you need to provide (override) LocalTextStyle with lineHeight = TextUnit.Unspecified

[Mark]

Oh right. I read that differently. By passing lineHeight into the style passed to `Text`’s style arg, you would be overriding `LocalTextStyle`’s lineHeight value. So I thought you meant that rather than providing/overriding through CompositionLocalProvider. Thanks for the clarification.

[Ivan Matkov]

Sorry if my message was unclear, I should have attached a code example
