Hi all. Someone can explain me why lazy column slow and skipping frames and when it will be fixed? 🙂

[Adam Powell]

Are you running a release build using r8? If not, do so; there are significant performance differences between debug builds, release builds, and optimized builds.

[Adam Powell]

Additionally, on initial process startup you may see some initial slowdown in development environments because the runtime profiles for compose and your app are not yet installed. https://developer.android.com/jetpack/compose/ergonomics#profile-inst speaks a bit about this, and we're looking to publish more info about the process and how to best run local tests under the same conditions you'll see in production.

[Adam Powell]

We are not currently tracking performance issues specific to LazyColumn that aren't addressed by the above; if you have a specific repro case that you think is not, please file a bug on the tracker

[Adam Powell]

@Andrey Kulikov may be able to give some more specific advice for your situation if you'd like to post some code
