In an exemplary aspect, a method for visual media processing includes determining whether a pair of adjacent blocks of visual media data are both intra block copy (IBC) coded; and selectively applying, based on the determination, a deblocking filter (DB) process by identifying a boundary at a vertical edge and/or a horizontal edge of the pair of adjacent blocks, calculating a boundary strength of a filter, deciding whether to turn on or off the filter, and selecting a strength of the filter in case the filter is turned on, wherein the boundary strength of the filter is dependent on a motion vector difference between motion vectors associated with the pair of adjacent blocks.
