Your observation confirms what I wrote earlier in this thread: The vertical lines are caused by a difference between the pixelclock used by Indivision AGA MK2 and the pixelclock that the flatscreen is using. This shifts the sample-spot in relation to the actual pixel, giving the effect that you're seeing.
You will be able to completely eliminate the vertical lines with the forthcoming config tool, as that will let you configure the output mode to a Vesa standard. The sampled pixels of the flatscreen will then be "on the spot" where Indivision AGA MK2 produces them, and you'll have a crystal clear picture. That same crystal-clear picture is already possible if you're using the DVI connection - a purely digital connection does not require any sampling and thus doesn't have the artefacts that come with sampling.
