In addition to what I mentioned in the original post; I’ve also tried turning off Legacy shading model; I tried turning Forward Shading off; I tried turning Instanced Stereo off; I tried turning on Chroma Correct; I’ve tried turning off Enable Specific Color Gamut; tried turning on the post processing settings; and I’ve tried deploying the shipping version.
None of these have fixed the issue.
I did more research and learned that the First Contact app uses the Unreal Engine, so I looked at that app and it DOES NOT have this problem. So surely there is a way to get this to work (unless it was a bug that was introduced in a later version of Unreal than the one used for First Contact).
