#493 closed defect (fixed)

chroma residue scaling cannot be enabled in I-slice IBC mode when DualITree=0 (non-CTC)

Description

In VTM6.0, the conditions to control chroma residue scaling (CRS) have issue to handle IBC mode for I-slice when coded in shared tree (DualITree=0). m_pcReshape->getCTUFlag() (which is set to false in intra slices and true in inter slices) should be removed from the conditions in inter-coding related processes to allow CRS to be enabled for IBC mode of intra slice when applicable.

This is no impact to CTC coding where DualITree=1 is set.
