Previously we always used the mask 0x03FF, while we now use 0xFFFF for 8 bit. I presume that means that for 8 bit, we mask two pixels with one 0xFFFF (and keep all bits), and previously we accidentally masked out everything but the lowest two bits, from every other pixel, in 8 bit mode?
The patch LGTM, but it'd be good to acknowledge this existing issue in the commit message.
