I have a LazyVerticalGrid composable with around 100 elements (2 columns) and the scroll is already very laggy. With a SmallAppBar and a scrollbehavior, it is now very very laggy.

Is this a LazyColumn/LazyVerticalGrid performance issue?
We've ported the behavior to material (not material3) and whenever LazyColumn's size and position were being adjusted during a scroll, the scrolling was laggy.
We've also tried to make LazyColumn fill the whole screen and adjust its contentPadding instead, but we got the same result. The scrolling was laggy while contentPadding was being adjusted.
Once the bar is collapsed, the performance seems okay again.
We use ExitUntilCollapsedScrollBehavior.

Are you testing on a debug or a release version of your APK?

We tried both. It's a bit better in release version but not good enough for production use.
We tested on physical Pixel 3a with API 32.

Could you provide us with a minimal code that showcase this issue. It can be very helpful!

Will keep this one open for now until the fix is merged and pushed for the next alpha.
Description
API checks and Java ecosystem recommends SQLiteConnection and SQLiteStatement to implement Closeable / AutoCloseable but there is no KMP common Closeable interface. Other art work has defined a expect Closeable in commonMain and have actual typealias to Java's interface and implemented utility function in native.
It would be also nice if we can add finalizers to close things and warn about leaks. JVM and Android has finalizer APIs (https://docs.oracle.com/javase/9/docs/api/java/lang/ref/Cleaner.html ) along with the soon-to-be-deprecated https://kotlinlang.org/docs/java-interop.html#finalize ) and in iOS there is https://kotlinlang.org/docs/native-ios-integration.html#deinitializers ). But I don't think there is anything available for native...
