07/04/2025, 6:15 AMEnsure you're testing your frame rate issues on a release build (compose optimizes a lot on release builds).
If it's still an issue - start looking into optimizing your composables. You might have a lot of unnecessary recompositions.
Personally, I'm also using Compose 1.8.2, and I'm seeing no issues whatsoever even on a debug build.

However same is in pure iOS app that we do have in production using SwiftUI
I could barely notice a difference TBH
