Jetpack Compose release version: 1.0.0-beta03

Steps to Reproduce:

Open compose samples
Navigate foundation -> lazy lists -> simple column
Fling very hard to bottom

Sometimes, when scroll stops, topmost Text composable lays out wrong, resulting in visual artefact, but snaps into place after new scroll. Example in attached video

This happens when there is multiple Text elements in the merged tree and we just take the first one and ignore the rest.

Marked as fixed.

I'm working on it this week. Note that the culprit is actually the big substantive patch I landed on Jul 3, http://aosp/1354246
