LazyGrid is a proposed name for the component allowing to display a list of items in a grid. Similarly to LazyColumnFor only the currently visible items will be lazily composed.

seems to be dup: b/212982460

Fundamentally the issue here is that the selection logic happening in composition depends on the text layout result which is available on measure. So we end up using stale TextLayoutResult which causes the issue.

This is the same exception as in b/229378536 and b/221580975 as well, and it also involves selection, so I'm wondering if those two bugs have the same cause Anastasia described.

Marked as fixed.

There is a similar problem regarding Magnifier but I don't think these are directly related. The main cause for this issue is the async relation between TextFieldValue and layoutResult. Magnifier related crashes don't seem to be caused by changes in TextFieldValue or layout.
