Summary0000168: Dithering of reference white with error diffusion
DescriptionOn all white images(RGB 255) and video (RGB 235 reference white) after dithering with error diffusion 1 or 2 in 8-bit mode, the outputted image consists of RGB 254 and RGB 255 pixels. It should only consist of RBG 255 pixels.

Using random dither or no dither gives only RGB 255 white pixels which is correct.
Steps To ReproduceLoad an all white image or try the AVS 3-White Clipping.mp4 test pattern with ED 1 or 2 enabled. Then use a image editor to clip the lower part of the histogram >250 to se the dithering of whites more clearly.
