Section 8.8.5.2 ""For the derivation of the filtered reconstructed luma samples alfPictureL[ x ][ y ], each reconstructed luma sample inside the current luma coding tree block recPicture[ x ][ y ] is filtered as follows with x, y = 0..CtbSizeY − 1"" Section 8.8.5.4 ""For the derivation of the filtered reconstructed chroma samples alfPicture[ x ][ y ], each reconstructed chroma sample inside the current chroma coding tree block recPicture[ x ][ y ] is filtered as follows with x = 0..ctbWidthC − 1, y = 0..ctbHeightC − 1"" The locations [x][y] need to be offset by the CTB position, otherwise it's just processing the top-left CTB over and over. Something like what is used in 8.8.5.7 seems more appropriate. " defect closed minor spec VVC D10 vE fixed ksuehring bbross XiangLi fbossen jvet@…
