Bad seeking of AVC YUV444p10 input

[HuangRuixiao-eng]

When I read YUV444 AVC clips in https://dmhy.anoneko.com/topics/view/365175_Nagi_no_Asukara_2013_BD_Vol_1-9_Fin_1080p_AVC-yuv444p10_FLAC_MKV_mawen1250.html with core.lsmas.LWLibavSource, it presented a wrong result after seeking and no waring or error report.

core.lsmas.Version() info:
{'config': b'-Dcachedir=""""', 'ffmpeg_version': [b'n4.4-dev-3785-g0f6745060e', b'Lavc58.134.100', b'Lavf58.76.100', b'Lavu56.70.100', b'SwS5.9.100'], 'version': b'vA.3e-0-g59ef222'}

The result is attached below:
