OpenGL Bug Generating Mipmap after getting TextureHandle causes texture sampling to return black at any other Lod than 0 if compressed format is used

Raw

AmdBindlessCompressedLodArtifacts.md

High level steps to reproduce:

Create a valid 2D Texture with compressed internal format
Upload some pixels
Generate a bindless texture handle
Generate a mipmap for the texture
Now in the shader, sampling the texture at every other LOD than 0 always returns black

Here is a minimal example that reproduces the issue: https://github.com/BoyBaykiller/AmdDriverBugReproduce/tree/master. It works by default, but when the variable shouldReproduceBug is set to true a black screen is shown.
