Application Build Memory Allocations massively different between 9.4.1 and 10.1

I have an application whose primary visual load is an NSTableView with layer backed views. When I build this app using XCode 9.4.1 and macOS 10.13 frameworks, memory allocations for VM: NSTextLayer (CALayer) run about 5-10 MBs. When I build the same project against XCode 10.1 and lastest OS frameworks, memory allocations for VM: NSTextLayer (CALayer) run about 350 MBs!


Would anyone have a recommendation on how to debug this? Is this an XCode 10.1 bug? The 10.1 build is not indicative of how the program peforms. Its an NSTableView and doesn't need 350 MBs!!

I am also seeing the same behavior in the 10.2 Beta.
