On the 6S, the SunTemple scene is almost unresponsive. As the player uses the thumbsticks, the lightmaps from the windows rotate to mach the player's movement; but they are the only thing.

This doesn't occur in 4.16 on the same device.
On the affected devices, I loaded the blank template level without any artifacting.

Devices this occurs on:
iPhone 6S on 10.3.2
iPhone 6S on 11

It does not occur on:
iPad Pro 9.7" on 11
iPad Mini4 on 9.3.5

Steps to Reproduce

1. Download Release 4.17 and the SunTemple showcase (on Windows)
2. In the editor, use File > Package to make the app
3. Deploy to a 6S and run it
4. Use thumbsticks to move around

RESULT: Most rendering in the scene does not update to reflect player movement.
