The testing routine used by selur converted back to 8bit to compare. A native 10bit waveform does not demonstrate the problem. But it's still a bizarre aggregation, and why this occurs at CRF 8 but not lossless.
I'll swap out and double check the decoders and encoders and do some more tests when I have more time
