For xIntraRecLumaBlk, possible correction can be like the following and similar for xIntraRecChromaBlk.

//===== inverse transform =====

if( pcCU->getCbf( uiAbsPartIdx, TEXT_LUMA, uiTrDepth ) )
{
	m_pcTrQuant->setQPforQuant  ( pcCU->getQP(0), !pcCU->getSlice()->getDepth(), pcCU->getSlice()->getSliceType(), TEXT_LUMA );
	m_pcTrQuant->invtransformNxN( piResi, uiStride, pcCoeff, uiWidth, uiHeight );

	Pel* pPred      = piPred;
	Pel* pResi      = piResi;
	Pel* pReco      = piReco;
	Pel* pRecIPred  = piRecIPred;
	for( UInt uiY = 0; uiY < uiHeight; uiY++ )
	{
		for( UInt uiX = 0; uiX < uiWidth; uiX++ )
		{
			pReco    [ uiX ] = Clip( pPred[ uiX ] + pResi[ uiX ] );
			pRecIPred[ uiX ] = pReco[ uiX ];
		}
		pPred     += uiStride;
		pResi     += uiStride;
		pReco     += uiStride;
		pRecIPred += uiRecIPredStride;
	}
}
else
{
	Pel* pPred      = piPred;
	Pel* pReco      = piReco;
	Pel* pRecIPred  = piRecIPred;
	for( UInt uiY = 0; uiY < uiHeight; uiY++ )
	{
		memcpy( pReco, pPred, sizeof( Pel ) * uiWidth );
		memcpy( pRecIPred, pReco, sizeof( Pel ) * uiWidth );

		pPred     += uiStride;
		pReco     += uiStride;
		pRecIPred += uiRecIPredStride;
	}
}
