Hi Soft8soft, I am trying to implement screen space reflections. They work well on all platforms that I have tested except for a Google Pixel 3 XL phone. On this platform, the material to which SSR is applied turns into a wild rainbow of colors. See the attached screenshot. This phone uses a Snapdragon 845 with an Adreno 630 GPU.
I have also tried this scene on an iPad and a Galaxy Tab S6. Both of these devices render the scene correctly. The Galaxy Tab S6 has a newer CPU and GPU than the Pixel 3 XL. The Galaxy has an Adreno 640 GPU.
