<pre>When uploading ASTC textures on gen9, we perform a workaround that involves
modifying the compressed blocks.
If these blocks are subsequently read via a texture download or CopyImage
operation, the result would not match what the user uploaded.
Another reason that CopyImage can fail is that the needed workaround is not
applied for CopyImage calls that have ASTC textures as the target. When the
ASTC texture is later read, we may encounter a rendering issue.</pre>
