I'm not sure if the developers are aware of this bug but I've had it a long time and have had to resort to glCopyImageSubData to avoid it. The issue occurs when you have a Texture of Format A and a Texture View of that Texture using format B. If I setup the TextureView as a renderTarget, the data rendered will be wrong and use the format of the parent texture. I have tested this in other drivers, including NVIDIA's and Intel's where it works correctly, so I'm assuming it's an AMD's driver bug.
