The first release of the CTS for AV1 decoding had incorrect offsets for the OrderHints values. The CTS will be fixed, and eventually, the drivers will be updated to the proper spec-conforming behaviour, but we still need to add a workaround as this will take months. Only NVIDIA use these values at all, so limit the workaround to only NVIDIA. Also, other vendors don't tend to provide accurate CTS information.
