I was able to reproduce it in a sample project. The FB number is FB17149864.

Some problem here. We are releasing a new version of our app, and we have to update the launch screen as well. After restarting my phone I was able to develop & test it, but when we release it to Test Flight our QA team has the same issues with non visible images. After they restart their phones the issue goes away and the images are visible. Now this makes me think if we release it to the App Store whether our users have to restart their phones as well? IMHO this unacceptable.
