Possible hevc 10 bit HW decoding bug in current drivers

Hi, i'm trying to decode and encode 10 bit HEVC using hardware on Kabylake i7 7700 processor, command line used

sample_multi_transcode -i::h265 "D:\Intel Media SDK Plugins\4K Demos\Samsung Journey Of Color 4K Demo.265" -o::h265 D:\TESTE.hevc -hw -async 10 -pe hevce_gacc -pd hevcd_hw -cqp -qpi 20 -qpp 22 -qpb 24 -u balanced -l 1 -gop_size 24 -dist 4 -num_ref 6 -bref -bpyr -ec::p010 -w 1920 -h 1080 -WeightedPred::implicit -WeightedBiPred::implicit -amfs:on -extbrc::implicit -pp

I'm on Windows 10, tryed the first media sdk driver release and the latest, both produce same problems, if i use hevc decode plugin from Media SDK 2018R1 it works perfectly but are too slow for decode > encode, i have uploaded the result hevc stream in attachment

Regards
