The issue happens when XBMC upon launch triggers a switch to the discrete GPU.

If XBMC launches and it triggers the switch to the the discrete GPU, it starts in 16bit color.
If XBMC launches and the GPU has already been switched prior to xbmc's launch to the discrete GPU, say by manually switching it in energy saver or connecting an external display(which always forces a GPU switch) then it starts in 32bit color.

So if you 1.Connect MBP to HDTV and 2.Start XBMC, the issue is bypassed.

Now for the banding issue with 10bit anime:

I used to see this issue on older macs with older Intel graphics GMA950 in my case, where if you used CoreVideo as video output, 10bit anime would look fine, but if you used OpenGL as output, you'd get the horrible banding.

So it all depends on how old Lemmy's Intel GPU is.

Hey! Yes, unchecking the "Automatic Graphics Switching" box in Energy Saver seems to have fixed this same issue for me. Thanks so much!!
