Landscape materials do not correctly render on iPhone 5S with version 8.3 installed

[JoshA] This is a bug in the Metal renderer. Basing on the screenshots in the Comments, it looks like some sort of precision issue in Metal shaders?

Landscape materials incorrectly render when deployed to an iPhone 5S on version 8.3. Previous versions installed on the 5S render correctly.
