1. A method of video processing comprising:
determining a coding mode for a candidate block associated with a current block in a current picture;
adding a block vector associated with the candidate block to a candidate list in response to the determined coding mode indicating that (i) the current block is coded in one of an intra-inter blending mode or a triangle prediction unit mode, (ii) a luma component and a chroma component of the current block have a same coding tree structure, and (iii) the candidate block not being coded in an intra block copy mode; and
reconstructing the current block based on at least one candidate from the candidate list.
