            <title>[MC-11530] Map Item Draws Slowly When Hanging in Item Frame</title>
                <link>https://bugs.mojang.com/browse/MC-11530</link>
                <project id="10400" key="MC">Minecraft: Java Edition</project>
                    <description>&lt;p&gt;I noticed my map hanging on my wall was drawing much slower then usual. I have been able to reproduce every time I re-hang it. It draws normal speed while being held but goes about a tenth of the speed while hanging. Note the time stamps on the images.&lt;br/&gt;
This video can describe it better:&lt;br/&gt;

                            <comment id="125402" author="quimoth" created="Mon, 16 Dec 2013 03:27:40 +0100"  >&lt;p&gt;Alright here is the part that really annoys me:&lt;/p&gt;

&lt;p&gt;i&apos;ve got 6 beautiful maps in item frames, but the only way to make the map load within a time span shorter then 10 minutes, is by taking each map out and load it separately by holding it in my hands. There is no excuse for bandwidth, since if taking them out and loading them one by one in your hands is faster that would mean mojang secretly added bandwidth. Also the map data most of the time is fixed, unless someone is building a lot and you have a copy of it so you &quot;explore&quot; the new buildings.&lt;/p&gt;

&lt;p&gt;i suggest that you should at least try to equal the time it takes to load X maps by hand to the time it takes to load X maps in item frames. (right now i have a chest with copies next to the map wall, this way you don&apos;t have to wait all day before the map has loaded)&lt;/p&gt;

&lt;p&gt;It is just like the chest minecart, you have beautiful ideas for it, but some game mech&apos;s make about half of the uses either a lot harder or impossible. Chest minecart will lose momentum and stop when it rides into an unloaded chunk, which means you can&apos;t even practically use it to transport items from your mine to your base unless you got an overload of pistons or hoppers to create lag creating and dangerous chunk loaders. This means that practically, you will only waste time since you use up just as much resources as you get and need to spend time into building the chunk loaders as well since you need to load the 5x5 area. Since the horse update, minecarts just aren&apos;t anywhere near a viable way of transport for either goods or players.&lt;/p&gt;</comment>

                            <comment id="118046" author="purple" created="Fri, 8 Nov 2013 00:57:17 +0100"  >&lt;p&gt;You are using as an example an impossible scenario. &lt;br/&gt;
Maps on item frames won&apos;t update their content/image unless the player removes it from the item frame and holds it in hand. Also it takes the same amount of time for a 1:1 and a 1:16 framed map to load. So as long as it is framed, it is a non-changing image. I don&apos;t see how it would affect performance (bandwidth or cpu usage).&lt;/p&gt;</comment>
                            <comment id="118045" author="talven81" created="Fri, 8 Nov 2013 00:40:11 +0100"  >&lt;p&gt;Think of it this way... do you want the 10,000 maps people have placed around to load quickly and jam up your connection or processor on a slower PC? This way only active maps are being drawn fast and the rest can display as the server or client has time to catch up.&lt;/p&gt;</comment>

If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.&lt;/p&gt;</comment>

                            <comment id="56046" author="purple" created="Thu, 21 Mar 2013 15:26:44 +0100"  >&lt;p&gt;My findings are:&lt;/p&gt;

&lt;p&gt;A discovered map in an item frame loads significantly slow unless a copy of that map is inserted in the inventory. While the copy is in the inventory, the map in the item frame loads fast as always. If the copy is removed from the inventory the loading speed of the map in item frame is slowed again.&lt;/p&gt;

&lt;p&gt;This video can describe it better:&lt;br/&gt;
