Burny

Walking into a map from the north, the position marker disappears "under" the map.

Since MC-33254 was moved here. I'd like to add the issue that was described there:

Maps also show no longer the current position if the error happens. This is surely related to the issue here,
but makes maps much more unusable than just a buggy green marker…

PS: I could resolve the issue with maps not showing my position. Since the private server I play on changed the Java version from 1.6 to 1.7 it works again.
PPS: Broke again after a while, was many just the server restart?

Description of Screenshots attached to MC-33254

1) Two copies of a map, the one that the player holds shows no position for him, but position of last item frame it was in.

2) Back at the former position the map still shows green marker of last position.
The map here is the same instance as in the first picture.

Never had issues in 1.6.x but first tried the maps in item frames in 1.7.2.
Now I have maps not showing my position.

I can still discover new territory, but the only marker I see is the item frame (as a white dot).

Retrieving all maps from the item frames does not change that.
Maps are also loading very slow after login.

Placing the item fame and the map at the center of the map area results in the correct green marker.
Still a copy of that map in the players hand shows the old item frame position and no player position.

Putting the frame and map back to the old location results in showing the green marker on
the last position, so we have two green markers what indicates a problem.

PS: I could resolve the issue with maps not showing my position. Since the private server I play on changed the Java version from 1.6 to 1.7 it works again.

PPPS: Found strong indication that position marker IS drawn, but behind the "map" pixels.
I was north of a map that showed no position and got a marker at the top.
Moving south, you can see this marker gradually disappear...
