1. A method of video processing, comprising:
performing a conversion between a video comprising a current picture and a bitstream of the video,
wherein the bitstream conforms to a format rule, and
wherein the format rule specifies that the bitstream comprises a flag for disabling a use of a temporal motion vector prediction tool for the current picture based on whether a reference picture in a decoded picture buffer has a spatial resolution and scaling window offsets that are identical to that of the current picture.
