Any update on this yet? I've run into the same problem, so I did some digging in the View Hierarchy debugger. Here's what I found (attached screenshots comparing this in iOS 16.4 to iOS 17). It seems like in iOS 17, there's a property called image in the "Image" section of the Object Inspector (4th tab in right-side panel while debugging view hierarchy). This image property has a parameter called maskColor that is set to (0.99999994, 0.99999994, 0.99999994, 1) (which is weird, because a mask shouldn't do anything if its transparency is 1). Meanwhile, on iOS 16.4, this image property is just set to <null> altogether. I haven't been able to programmatically replicate this effect in iOS 16, but do with this information what you will (maybe add it on the feedback report if nothing is updated on it yet). iOS 16.4: iOS 17:
