Wall of maps in item frames causing extreme lag after 1.9 update

When investigating this on Windows 10 there was very little to no lag. I'm currently running on HP Intel Core i7 Nvidia GeForce GTX 1070. Switching over to Xbox X frame rate was very low. Freezing at times. While removing maps in the 13x13 frame. Frame rate was not noticeably better until we got to our last row of 13 maps. The notebook would crash players game when pick blocking on both versions. Had to break and replace to be able to pick block.

Please contact Mojang Support and provide the Realm info they request if you require help with issues specific to your Realm.

Jay, asked to post this as a bug, since we are Volunteer Moderators for the Official Community Realm 🙂

Oki doki 😃

Moved to the Bedrock section as this issue was reproducible in a local copy of the world also. Updating title.

I can confirm the loss of framerate occurs in Bedrock version for Nintendo Switch as well, and has been affected since about Minecraft 1.8.0. The closer you are to the map wall, with it in your field of vision (even if behind walls and floors where you can't actually see it) the slower your framerate down to estimate of around 7fps sometimes. The slowdown happens even when you scan your field of view across the map wall from well over 60+ blocks away. A character looking in the general direction of the map wall experiences the framerate drop even if it is not visible due to obstructions or landscape.

What even is the community realm?

This issue also affects Bedrock Dedicated Servers.

Still having this same issue on the Nintendo Switch release of the Bedrock edition. A wall map in our town causes lots of stuttering whenever I look in that direction.

This is still an issue/ After getting about half the map wall up frame rate starts dropping. On the Community realm and my personal world.

This is still an issue as of 1.12

Items frames are still a issue.

I have a 9x9 set of maps in item frames on the floor. When I am near the chunk containing the maps, whenever I look in the direction of the maps there is severe frame-rate lag. When I am looking in the opposite direction there is no problem. 

While the problem definitely occurred before 1.14, it became much more severe when 1.14 dropped.

My players on BDS are experiencing this as well, but with item frames containing items, not maps. We have approximately 200 item frames with items in a storage room, FPS drops whenever you look at it on xbox or the switch. Some players are experiencing it on PC as well, but not all.

I'm having The same problem too with maps in item frames. The frames would just drop when I'm near them Even in this current version 1.14.30.

Pretty much same issue as others reported, 7x7 map on the floor of my spawn area. It’s a single player world, playing on Xbox one

I am experiencing this in a realm with version 1.14.60. I built a 28 block diameter round building with multiple floors. The ceiling of the lower floor is a lit up white drop ceiling created by placing Jack o'Lanterns on top of slabs, then removing the slabs and placing an item frame and map on the bottom of each Jack o'Lantern. The maps were created by levelling an entire 128x128 (map size) tundra field to create an all white map. Then used an anvil to change the map name to a space character, then made enough copies of the map to cover the ceiling. The top of the Jack o'Lanterns is covered with carpet and is the floor of the second story. Now I see lag when eating food or breaking blocks. When breaking blocks the item breaks but jumps around for several seconds before it finally falls to the ground. The attachment Minecraft 4_19_2020 10_10_22 shows the room with the large map filled ceiling.

I've tracked the lag effect on a nearby furnace piston feed tape. With the ceiling maps in place the four pistons would cycle once every 5.5 seconds. After removing the 418 maps, but leaving the item frames in place, the piston feed tape would cycle every 1.7 seconds. So the maps were causing 3.5x slower piston operation as well as other overall lag. It should be noted that two other players on the Realm, hundreds to thousands of blocks away reported bad lag when the maps were in place. One reported that he couldn't even fire a bow.

Having the same issue on our Realm running 1.14.6 on Xbox One. Do we have any fix?

This issue is reportedly fixed in the Beta test release. Unless a serious flaw with the fix is discovered, it will likely be included in the next public release. However, no date can be given for the release.

Resolving issues that were marked as fixed in the 1.15 and 1.16 Betas, now that 1.16.0 is being released.
