I've notice that at some chart scales, SkyDemon doesn't show lakes, not even very large lakes like Sweden's Vänern which is essentially an inland sea. This is confusing since other terrain is rendered.

After some testing it appears that at scale 1:2 000 000, lakes are never shown. At scale 1:750 000, lakes are always shown. At scale 1:1 000 000, lakes are shown if they were before changing the scale. I.e. when going from 1:750 000 to 1:1 000 000, lakes in the current view will be shown, but if I move the view to a different area, lakes will not be shown.)

I've primarily tried this with the SkyDemon 2 chart style, but it seems to happen with all chart styles.

I'm using SkyDemon 3.3.1.0 on a PC.
