576	bCTUboundary condition for CCLM filtering incorrect	bheng		"The isFirstRowOfCtu condition is calculated in xGetLumaRecPixels( ), as shown below:

    isFirstRowOfCtu = ((pu.block(COMPONENT_Cb).y)&(((pu.cs->sps)->getMaxCUWidth() >> 1) - 1)) == 0;

Here it uses the vertical position of the PU rather than the vertical position of the TU.  For implicitly split TUs within a PU (due to maxTrafoSize), this can give the wrong result.

I believe something like the following would fix the problem.

    isFirstRowOfCtu = ((chromaArea.y)&(((pu.cs->sps)->getMaxCUWidth() >> 1) - 1)) == 0;"	defect	closed	minor	VTM-7.1	VTM	VTM-6.2	fixed		ksuehring XiangLi fbossen jvet@…
