1. A method of video processing, comprising:
determining, for a conversion between a current block of a current picture of a video and a bitstream of the video, whether to disable a refinement coding tool for refining a motion vector or a prediction sample for the current block by an offset value; and
performing the conversion based on the determining,
wherein the refinement coding tool is disabled when a dimension of a reference picture of one or more reference pictures of the current block is different from a dimension of the current picture, or a dimension of a scaling window in a reference picture of one or more reference pictures of the current block is different from a dimension of a scaling window in the current picture.
