Issue
When using resource pack that utilizes Core Shaders feature (such as Energy Shaders) every non-entity texture becomes invisible, which did not happen before. Screenshots are showing the issue and the resource pack screen.
Expectations
Textures are not becoming invisible just because you are using a Resource Pack that utilizes Core Shaders feature.
