I'm not sure about this.

This mistake could easily have been in other vendors Linux GPU drivers, they in the end don't have nearly the same priority (and in turn resources) as the Windows GPU drivers. And it's a very easy mistake to find. And I don't know if anyone even cared about ray tracing with Intel integrated graphics on Linux desktops (and in turn no one profiled it deeply). I mean ray tracing is generally something you will do much less likely on a integrated GPU. And it's a really easy mistake to make.

And sure I'm pretty sure their software department(s?) have a lot of potential for improvement, I mean they probably have been hampered by the same internal structures which lead to Intel faceplanting somewhat hard recently.
