Description

The licensee reported "Nearest" filtering on Vulkan doesn't work on some kinds of Android devices.
[Link Removed]

I was able to repro this issue on Pixel3 but wasn't able to repro it on Xperia X Performance.
Licensee tested it with some other devices.

In summary...

Device Work Correctly?
Pixel3 XL No
Xperia X Performance Yes
Galaxy S9 No
Xperia XZ1 No
Mate 10 Pro Yes
Steps to Reproduce
  1. Open the attached project
  2. Launch to Pixel3 (automatically uses Vulkan)
  3. You can see a blurry grid pattern texture even though the texture's filtering setting is "Nearest".
  4. If you lunch the map with OpenGL, the grid pattern is sharp.
