This could potentially apply to other error-diffusion algorithms as well. This could possibly be due to rounding error as well. Regardless, when error builds up because a region's colors are similar, it spills over and creates dividing lines that can further spill over, giving an extremely incorrect output. The source image had either 6 or 7 colors only.
