This is http://quality.livecode.com/show_bug.cgi?id=9992 - back when 
this was reported there was no way to do as you are wanting. However, it 
seems like since then there is a new way to get a snapshot of the 
screen:

https://developer.apple.com/documentation/uikit/uiview/1622589-drawviewhierarchyinrect

So we can try that to fix the problem (it might still not work for some 
layer types).

Warmest Regards,

Mark.
