Scrolling through LazyColumn or VerticalPager with AndroidView filling the whole screen as a child item lags the screen and the scrolling behavior for a couple of milliseconds as well as overlapping items. Is there any way to optimize creating an AndroidView composable?

Over to Ralston to take a look. I imagine with the new relocation logic it should be fixed?

What is happening here is that the TextField does not know that it is in a scrollable container, and since the keyboard is going to hide the currently focused text, the text field calls View.requestRectangleOnScreen which causes the entire app to pan up, and that clips the top bar.

The Relocation APIs are experimental right now. It is not used in TextField as we are past the alpha stage and can only use stable APIs in TextField. So this bug can only be fixed post 1.0
