When an image is encoded in YUV NV21 format, visual artefacts are visible on certain Android devices.
Steps to reproduce:
1) Open the attached project.
2) Set the Graphics API to OpenGL ES 3.0.
3) Build & Run on an Android device (Galaxy S7/S7Edge w/ Android 7).
The image is striped and discolored. This does not happen with OpenGL ES 2.0 and Vulkan. Not all devices reproduce this issue.
