On Tigerlake and later, we enable compression for image views. However, we never actually added any code to update the aux state, which meant that if it ever changed, things would break, badly. We managed to avoid catastrophic effects in most cases because of two other issues which papered over the problem: if compression wasn't already enabled for an image, we'd leave it disabled. And, we avoided writing via the CPU to buffers with auxiliary. So in most cases, CCS remained disabled, or got enabled (say by glTexImage()) then stayed on permanently. There were still issues, but they managed to remain more hidden than one would expect given the severity of the bug.
