1. A method of coding a video sequence, executable by a processor, comprising:
receiving video data including one or more faces;
selecting one or more virtual boundaries between the one or more faces of the received video data, wherein a distance between two virtual boundaries of the virtual boundaries is a number of luma samples that is greater than or equal to a size of a coding tree unit (CTU) associated with the video sequence; and
disabling in-loop filtering between the one or more selected virtual boundaries, wherein at least one of the one or more virtual boundaries is selected by determining a distance between an i-th virtual boundary along an axis and an (i-1)-th virtual boundary along said axis.
