34	intra-fast encoder-side decisions based on possibly incorrect obmc pred buffer	gordon		"Present in jem4.0 rc1.
In TEncCu::xCheckRDCostInter obmc is tried 'on', then 'off'.  When it's tried 'off' it uses a different prediction buffer that is not saved in rpcTempCU.  If this becomes the winning candidate after xCheckBestMode, this ""wrong"" prediction buffer is used in a later JVET_C0024_PBINTRA_FAST test in xCompressCU.

The attached patch seems to correct the problem, but needs to be verified.
Compression gain differences on 17-frame RA tests we've done show very small average differences, but with variations up to +/- 0.3%"	defect	closed	minor		JEM	HM-16.6-JEM-3.2	fixed	obmc, intra-fast, encoder-side decisions	ksuehring XiangLi jvet@…
