When I upgraded to Sequoia 15.1, an app that worked fine under OS 14 stopped working. Out of 4 views on the main screen, only 1 is visible. Yet, if I click where another view should be, I get the expected action so the views are there, just not visible. Only I can't see where I am clicking!

I had to upgrade to Xcode 16 to recompile the app and run it in Debug mode. When I do, I get the following:

NSBundle file:///System/Library/PrivateFrameworks/MetalTools.framework/ principal class is nil because all fallbacks have failed.

Can't find or decode disabled use cases.

applicationSupportsSecureRestorableState

FWIW - the only view that actually shows up is the last subview added to the main view.

Upon further investigation, the issue is that only the last subview added to the main view appears, although the others are there. Simply changing the order in which the subviews are added changes which subview is visible.

Is this a bug in Sequoia 15.1???

Is there anything you can tell me about this issue? Does Apple recognize it as a bug in Sequoia 15.1?
