    Resolution Note (fix version 2020.2):

    Mirror Once texture wrap mode requires and OpenGL ES extension (which is supported on ShieldTV only) or a Vulkan extension (VK_KHR_SAMPLER_MIRROR_CLAMP_TO_EDGE_EXTENSION_NAME), which is not supported on all drivers.
    We fall back to Mirror wrap mode if it's not supported.
