It looks like the refresh rate switching API may have changed. It is actually switching to 24.000Hz and not 23.976Hz. If you try to manually set it 24.000Hz and change the colorspace to YCbCr 4:4:4, it completely breaks the refresh rate switching. It doesn't seem to be isolated to Kodi/SPCM. It is happening with Archos Video Player also.
Right now, the only solution is to set it to 23.976Hz mode in Shield's HDMI settings.
