I've encountered the same issue.
After testing, we found that running 17.4 (Beta1 ~ RC) on the simulator works fine.
Xcode 15- Beta and iOS 17.4 can be found in: https://developer.apple.com/download/all/
Maybe this problem has been resolved in iOS 17.4?(Running 17.4 RC on an actual iPhone 15 also displays correctly.)
Hope this information is helpful to you.
