Map re-drawing is laggy

So since the recent update, the map redrawing is incredibly laggy. Sometimes it just plain shows the wrong map.

When I open my big world map, it either gives me some other zone, or it gives me a blank zone for a good 5 seconds before it can redraw itself to where I really am. I still see all the quest areas and my own pointer in the right places, it's just the map drawing underneath is wrong or lags.

Anyone else seen this?
