Based on Compose Compiler Metrics, it seems `Painter` and `Icon` are unstable and keeping the function as non-skippable. Any ideas how else I could optimize my Coil Image Grid? Or does coil already able to optimize this somehow. It’s quite slow

Can you please share the Composable signature? Are you passing a painter and icon to each item in a grid?

It looks like this
```restartable scheme("[androidx.compose.ui.UiComposable]") fun Thumbnail(
  unstable painter: Painter
  stable contentDescription: String?
  stable modifier: Modifier? = @static Companion
)```

It’s for each `item.thumbnailUrl` -&gt; Thumbnail( `rememberImagePainter(Any)` )

Are you using Coil 1.x? I think they made big performance changes in 2.x. Might be worth testing the upgrade

Also, is there a reason the painter is hoisted and you aren't just passing in the url which would be stable?

Yes, Coil 1.0. `Thumbnail` is just a wrapper to `Image` and we use `rememberImagePainter`.
That’s a good point though, we pass either `Painter` or `Any`, but I’ll try passing stable params `String` as much as possible.
I tried Coil 2.0 before as a draft and there were actually performance improvements (though the huge janks were still there in my previous thread)
