The current 3D-HEVC text specifies following post filtering conditions for DBBP
if( ( lFlag | | cFlag | | rFlag ) && ( !lFlag | | !cFlag | | !rFlag ) )

filt = ( p[ Max( 0, x − 1 ) ][ y ] + ( filt << 1 ) + p[ Min( x + 1, nCbSX − 1 ) ][ y ] ) >> 2

if( ( tFlag | | cFlag | | bFlag ) && ( !tFlag | | !cFlag | | !bFlag ) )

filt = ( p[ x ][ Max( 0, y − 1 ) ] + ( filt << 1 ) + p[ x ][ Min( y + 1, nCbSX − 1 ) ] ) >> 2

However, the condition in "if" is opposite to the HTM11.0. It should be changed to
if( !(( lFlag | | cFlag | | rFlag ) && ( !lFlag | | !cFlag | | !rFlag ) ) )

filt = ( p[ Max( 0, x − 1 ) ][ y ] + ( filt << 1 ) + p[ Min( x + 1, nCbSX − 1 ) ][ y ] ) >> 2

if( !(( tFlag | | cFlag | | bFlag ) && ( !tFlag | | !cFlag | | !bFlag) ) )

filt = ( p[ x ][ Max( 0, y − 1 ) ] + ( filt << 1 ) + p[ x ][ Min( y + 1, nCbSX − 1 ) ] ) >> 2

In further, because the condition in "if" can be simplified, I suggest it is changed to

if( lFlag != cFlag | | cFlag != rFlag )

filt = ( p[ Max( 0, x − 1 ) ][ y ] + ( filt << 1 ) + p[ Min( x + 1, nCbSX − 1 ) ][ y ] ) >> 2

if( tFlag != cFlag | | cFlag != bFlag )

filt = ( p[ x ][ Max( 0, y − 1 ) ] + ( filt << 1 ) + p[ x ][ Min( y + 1, nCbSX − 1 ) ] ) >> 2
