I made a blank map in vanilla...

Steps:
1. Go to the nether
2. Create map in nether
3. Expand the map in a crafting table by surrounding map with paper
4. Take map out but DO NOT look at it
5 Go to overworld
6. Look at map
7. To get rid of the arrow, relog

Also, Item Frames "bulge" when the glitch map is placed inside.
