Generaly, if you keep the dither intensity to 0.5
(that amounts to a noise amplitude of one 8-bit
sample, ranging from -0.5 to +0.5 for a given sample)
there shouldn't be any flickering. Even if the dither
intensity is raised to 1 (i.e. covering two 8-bit
samples), the noise is nearly imperceptible. In any
case the aliasing artifacts that result from no
dithering are, IMO far, far worse then the extremly
subtle artifacts of the dithering noise. It's like
having film grain, just a tiny bit harsher.
P.S. Since I don't have CVS access, if the developers
find the dithering implementation good enough, it
would be great if somebody could add it to the main
