  "message": "rtc: Fix to color artifacts under high motion\n\nFor RTC: the golden reference is used as longer-term\nreference, but the color_sensitivity flags are\nonly defined relative to the last reference.\nThis can cause color artifacts for high motion\nif golden is selected as the best reference and\nhas different uv-signal than the source.\n\nThe fix here is to define a color_sensitivity for\ngolden reference at the superblock level, and for\nnow skip testing the golden reference if this\ncolor flag is set. Logic is also based on source_variance\nand content_stats, to avoid any regression from too\nmuch/unneeded skipping.\n\nThis reduces color artifacts in the issue below.\nTo reduce further: logic above on golden-ref can be better\ntuned, and defining color_sensitivity for alt-ref would\nalso be needed, but since alt-ref is closer to last ref,\nthe impact from that is less.\n\nStats changed are neutral/small:\n               avg-psnr  ovr-pnsr  ssim   IC-speedup\nspeed 7 derf:   0.03      0.03     0.05   -0.01\nspeed 9 derf:   0.15      0.18     0.18   -0.15\nspeed 9 rtc:    0.25      0.23     0.33    0.03\nspeed 10 rtc:  -0.01     -0.02    -0.03   -0.14\nspeed 10 screen:0.26      0.09     0.34    0.04\n\nBug: aomedia:3308\nBug: aomedia:3313\n\nChange-Id: Ie23ab25d8189540ea11d95c46cf9ea4f549c583d\n(cherry picked from commit c6a503f4b15da2ecef856f917d08473ea788ae00)\n",
