I think the problem fixed by the VGC upgrade was color fringing. Moire-like effects are almost certainly due to aliasing between the raster and the luminescent color dots on the CRT surface. You can clean that up to some extent by proper alignment of the CRT circuits, but I doubt that you can ever completely eliminate it. (There are also very expensive color monitors that don't have such problems.)
