Description

In spec text D7 vE, colPredMode[xColCb][yColCb] is used to determine collocated coding block's pred mode, while in VTM (xColCb, yColCb) is aligned to 8x8 first.

Suggest to change colPredMode[xColCb][yColCb] to
colPredMode[(xColCb >> 3) << 3][(yColCb >> 3) << 3]

Agree. Motion field compression also includes the compression of CuPredMode[][] of the reference picture.
