As you move, the ground tiles appear to increase saturation, or become 'dirty' like a bad multiple exposure.
This affects some types of ground more than others. Going to map and back again clears the 'dirty' tiles.
It looks like all tile-drawing has a kind of additive effect in 16bit mode.
Here are some successive screenshots taken as I moved around:

Here's a close-up which shows the 'stippled' effect:
