      Mod Notice

      We are now closing this issue, because it has grown too indistinct. Note that Mojang is aware that this is still an issue but the contents of this report have grown outdated or unclear

      If you still are experiencing this issue, please identify what the scenario is and submit specific bugs, so separate issues can be tracked separately. Also please make sure to include debug reports and all relevant information when reporting such bugs.

      Note: Jira is not a discussion forum. If you have performance issues, follow the instructions above rather than posting further comments on this issue.

      This bug can have multiple symptoms, including, but not limited to:

      • Crossing chunks in certain directions (MC-229115)
      • Rendering with generation
      • Entities spawning with generation
      • Biome identification (layed out in this comment)
      • Blocks rendering with different geometry (MC-261698)

      Also, when this issue occurs, the a line like this:

      Can't keep up! Is the server overloaded? Running 5000ms or 100 ticks behind

      will be printed occasionally in the game console.

      Sometimes this issue will become so bad that it will crash the server. In that case the crash report usually has a line like Description: Watching Server.

      If you experience this issue, please run a complete debug dump by following these steps:

      1. Generate a debug report (Client Side):
        • Press F3 + L
      2. Generate a debug report (Server Side):
        • Run /perf start
        • Wait then run /perf stop

      Those files will be generated in the debug folder of your Minecraft instance. If you are on singleplayer, access your game directory. If you are on server, report to your system administrator. If you don't have op permission, either ask your server admin to perform the dump, or if you are on singleplayer, open your world to LAN with cheats on.

      The game stutters when crossing chunk borders while moving quickly, for example flying with an elytra. With my configuration, this was noticeable with a render distance of about 13 or more, while I was able to play on 1.14 with a render distance of 20 or even more without any stuttering.

      Chunks at the edge of the render distance seem to be loaded all at once when entering a new chunk, which might contribute to the stuttering.

      On 1.15-pre3 the stuttering is less noticeable, but can still be observed.
