583	Mismatch between SW and Spec on enabling PDPC	chiaming		"In 8.4.5.2.14, the following are used to derive nScale for PDPC:
 The variable nScale is derived as follows:
 – If predModeIntra is greater than INTRA_ANGULAR50, nScale is set equal to Min( 2, Log2( nTbH ) − Floor( Log2( 3 * invAngle − 2 ) ) + 8 ), using invAngle as specified in clause 8.4.5.2.12.
 – Otherwise, if predModeIntra is less than INTRA_ANGULAR18 and not equal to INTRA_PLANAR, nScale is set equal to Min( 2, Log2( nTbW ) − Floor( Log2( 3 * invAngle − 2 ) ) + 8 ), using invAngle as specified in clause 8.4.5.2.12.
 – Otherwise, nSacle is set to ( ( Log2( nTbW ) + Log2( nTbH ) − 2 )  >>  2 ).

It should be corrected to
 The variable nScale is derived as follows:
 – If predModeIntra is greater than INTRA_ANGULAR50, nScale is set equal to Min( 2, Log2( nTbH ) − Floor( Log2( 3 * invAngle − 2 ) ) + 8 ), using invAngle as specified in clause 8.4.5.2.12.
 – Otherwise, if predModeIntra is less than INTRA_ANGULAR18, [[span(style=color: #FF0000, and predModeIntra is not equal to INTRA_PLANAR and INTRA_DC)]], nScale is set equal to Min( 2, Log2( nTbW ) − Floor( Log2( 3 * invAngle − 2 ) ) + 8 ), using invAngle as specified in clause 8.4.5.2.12.
 – Otherwise, nSacle is set to ( ( Log2( nTbW ) + Log2( nTbH ) − 2 )  >>  2 ).

Actually the issue had been reported in #489, but was not completely fixed in the latest spec (i.e., JVET-P2001-v8).
