The bug
Maps seem to update rather slowly/erratically, especially when compared to other items in the game like compasses, and defies the expected smooth movement. This applies to player movement, rotation and more.
How to reproduce
Hold a compass
Fly very closely past the area the compass points to - this could be either the world spawn or a lodestone it's attached to
Note how the compass is capable of changing smoothly and rapidly to give an accurate direction
Now create a fully zoomed in map, look down and move fast, such as by flying
Notice how the map is much slower to update, only updating the marker position every third of a second or so
