[MC-133294] Map Markers blacked out

Markers placed in specific chunks of my world seem to be permanently blacked out. Making a new map, new banners, different colored banners or placing banners in different spots in the general location doesn't seem to fix the problem. On older maps generated in the snapshots all markers including map and player locations are blacked out, while newly created maps in pre-release 7 only have the banners blacked out in certain chunks. Banners placement range from buried underground to above ground with complete view of the sky. Hoping this isn't just a bug with my world.

For me, any marker on the map that has a named banner is black, except those made before the named banner was added. Also, all people who hold a map remain on the map even after they have left the game until the server is restarted. I also see someone's marker on a second map that I made despite them not holding that same map, and they continue to be on it after they have left the game.

If you compare my first and second screenshots you'll notice the map marker in the center is now black. For a while after the named banner was placed I was still gray while everyone else turned black, and that map marker was still green until we restarted the server, which removed the markers of the people who were disconnected and also turned the green marker black.

I believe that any time someone disconnects and reconnects it was resetting their map marker to black which is why mine stayed gray for the longest (it's my server), and that the culprit is the named banner.

Edit: I tried removing the named banner from the map and the colors of all other markers reappeared, however the markers of people who were disconnected did not disappear so that issue is unrelated.

I was placing yellow banners to mark the path of an intended build and they appeared yellow in some chunks and black in others. In addition, named banners (all white) appeared white in some chunks and black in others. Highly irregular!

In my testing it definitely seems like every banner added after the first named banner appears black. If you remove the first named banner then the problem moves to the second named banner that was added. This means it's impossible to have more than one correctly-colored named banner on the same map.

The player's marker is affected the same way - if their marker is added to the map after a named banner, then it appears black as well. Removing any named banners added before the player was added fixes the player's marker as well.

Not sure if this is the same issue or a related one, but I also noticed that banner markers sometimes don't get saved properly and disappear after logging out and back in again. The pattern doesn't seem to be consistent though.

Confirmed that this still happens in 18w30a

I've had the same problem and its been bugging me a lot. I've also had the problem where banner markers don't get saved properly even though the banner was never taken down.

To add to what other people have said, we did have a banner not be saved on the map properly but it only happened once and it was the first time we added a banner. However, I've been rather consistently seeing all kinds of bugs with maps on my server, the most prominent of which are MC-134273 and MC-134274 in addition to this one.

This is "sort of" fixed in 17w30b - the markers aren't actually black any more, but I'm pretty sure they're darker than they should be. Also some of them are still disappearing when I log out and log back in again. See https://imgur.com/a/ugewLwj

Yep, they look clearly darker to me in your screenshots, haven't got time to test it myself though. Could someone reopen this?

Also, I've had the problem with disappearing map markers too in my LAN world after converting it from 1.12.2 to 1.13, it's really frustrating. The bug seems to be specific to certain random locations, so far I couldn't find any relationship to specific coordinates, chunk borders, banner orientations or names. Is this issue already reported in a different ticket? If not, could someone make one (I'm on my phone right now) and upload a world where this happens that isn't 400 MB in size?

Found the issue still existed with maps that were on item frames, but fixed for those that were held in hand. Fixing both cases now 🙂 Also, think I tracked down the saving issue as well, so if you want to create an issue for that one I can get it fixed!

Thanks for looking into this 🙂

I also noticed that maps in frames had issues with map markers and possibly the whole map looking darker than normal and I just assumed it was intended so I didn't mention it.

pizza2004 2018-07-28T04:15:10Z

Looks like the stuff when it's in frames might be another bug, namely MC-130258, although it could be related to MC-72866.

MC-72379 is another map bug I've been encountering lately that makes it difficult to know when you're actually off the edge of the map and it's safe to create a new one. Doing a bunch of maximum zoom maps with reducedDebugInfo means I have to just keep running after my cursor turns into a circle for a while to make sure I'm actually on the new map.
