What about having two fields with a small amount of overlapping (same) text and as the first field reaches the end of its scroll, the second field could be displayed and begin its scroll…

Changing the size of the text that is not visible during the scroll… though (the more I think about that one the more it seems like it would make the scroll wacky in other ways)  Neither seems super-promising but that’s all I can think of at the moment. If you find a solution, I would love to know what it is.

>>> Yes, that seems to be the problem. I have a long text field that exceeds the maximum. There's an enclosing group to be compatible with acceleratedRendering on mobile. The same setup is used for all the field/group combinations in the stack and they all work except this one, but the others are all shorter.

>>> I discovered today that if I set the behavior on the field instead of its enclosing group, I can make it scroll. But acceleratedRendering on a field is jerky and doesn't work very well on mobile. I can't break up the text, it has to be all one block. I have tried setting the group to container layermode without success.
>>> If you're wondering why the text exceeds the maximum, this is for a mobile app and there is not only a lot of heavy formatting with large headings and spaceBelow, but the text size is largish so that it is readable on a tiny phone. That makes the pixel count pretty high.
