[Android][GLES2] Artifacts in sampling reflection probes (problem with textureCubeLodEXT)




Priority: 2Necessary for shipping a final release


Severity: 3Secondary functionality broken

How to reproduce:
1. Open attached "ReproCorridor" project
2. Build&Run project to Android

Result - Materials are rendered with artifacts (look pixelated?) on devices

Reproducible with - 2019.1.0a13, 2018.3.1f1, 2018.3.0a6

1. Did not reproduce the issue on Vulkan or OpenGLES3, also did not reproduce the issue on iPad Mini 4 with GLES2. Standalone Windows build with OpenGL2 also diidn't exhibit the issue.
2. Removing reflection probes from scene (and adding directional light to scene, so it wouldn't be rendered in black on devices) solves the issue
