On android for some reason our display metrics for the application, activity and winow were smaller than the decor view. We were using the root view as the base static view for the visualiser with overflow hidden. Since it will slightly smaller than the decor view we were losing some of the lower pixels of the snapshot
The decor view is the one that is actually snapshot so any bounds for nodes above are meaningless . The fix is to simply have the visualiser start at the snapshot view. We know this bounds is correct.
Tested on ios and android and all looks ok
