      Most of this behavior can be reproduced near the world border: /tp 29999950 29999950
      Some of the strange rendering can also be seen closer to the center of the world but not in such an extreme way.

      Reason for this bug

      The 32-bit float simply run out of resolution/accuracy with the large coordinates. The solution is a bit of "ugly", but it got the work done, as I'm looking at perfectly fine wires at coordinates near X&Y of 17,000,000.
      There are more unnecessary (and sort of harmful) (float)-casts in that same method, but they are for Y-coordinates, and since Y-coordinates are, for the time being, very limited, they do not show similar problems. (That whole class seems to be littered with those float-casts, many of which seem to be unnecessary and possibly causing similar issues for other blocks/visuals.)

      Other bugs caused by this

      Fix for fire's smoke
      This time no source code as the changes cover almost the whole method. But its the very same fix, in BlockFire.randomDisplayTick(), change floats to doubles and remove casts to float when the variables are handling coordinates. This also includes sound generation coordinates.

      Affected entities, blocks or particles

      The following is based on a decompiled version of Minecraft 1.10 using MCP 9.30.

      Falling blocks

      The offset is probably caused by the method net.minecraft.client.renderer.entity.RenderFallingBlock.doRender(EntityFallingBlock, double, double, double, float, float). The texture being too large, shifted and rotated is caused by something else.


      Apparently only affects particles created under certain circumstances

      • Landing particles, see MC-76810 created by TheMoogle
      • Particles created by the /particle command
      • TNT explosion particles
      • Green bone meal particles
      • barrier particles
        • MCP 9.35 rc1 name
          Method: net.minecraft.client.multiplayer.WorldClient.showBarrierParticles(int, int, int, int, Random, boolean, MutableBlockPos)

      Rain and snow

      Rain and snow renders as large white lines when you are at a very high y-coordinate. This does however only happen for large y, but not for x or z coordinates.
