I think it can be anywhere, not just the card. The trick is, the
layermode must be set on the topmost object; if it's a group, then set
it on the group itself, not the contents of the group.

I'm not sure where it is now, but it was mentioned in the release notes.

I'm not sure how it would work in that case. If you have more than one
scroller in the group it could get tricky, and I think you're right
that's where the jerkiness comes in. My fields haven't been in groups,
so that's why I didn't see it.
The dictionary has a good explanation of how layermode works, maybe that
will help you figure out what to do. It doesn't specifically address the
kind of grouping you need to do though.
