This one is "easy" to explain but hard to fix.

The individual images are indeed correct; I suspect that the map context you 
are rendering into:
- does not match exactly the crs used by the tile set - we are rendering as 
grid coverages which can resample the image between projections
- does not match exactly the zoom level of the tileset (this is why 
applications like open layers have fixed zoom levels)

In uDig we changed our zoomIn/zoomOut buttons to respect the zoom levels of the 
data for these cases; and had to make a seperate pan tool that respected the 
resolution (usually if you just "pan" your bounding box you will gradually 
change scale; and thus the screen will not match exactly the resolution of the 
tileset).
