Chunk Loading is Unstable (Render Errors)

I have encountered this as well. Unlike the chunk loading issues in previous versions (where the chunks would all load, but in the wrong order) these chunks never load until you get within ~30m of them or force a rerender with F3+A.

Switching from "OpenGL: Fancy" to "OpenGL: Fast" seems to prevent or greatly minimize this bug.

This isn't actually a chunk error by definition; this is a render error. A chunk error would slow you when you fly over it, and have sides of whatever block was around them, just darker. These render errors have clear sides and render correctly when you get near them. This has been an issue in Minecraft for ages, but they are much more frequent in 14w17a. This is especially visible when in gamemode 3, flying around at max speed.

@John Roush Yeah I always have to reload the chunks

@AJ Ruckman Thanks, I knew it wasn't a Chunk Error but I forgot what it was called but I just renamed the problem.

Those strip shaped ones have been a regular bug in every version of 1.6, 1.7 and 1.8. When they eventually do load they sometimes load the parts of the chunk closest to your height first. I was pointing those out in some conversation about cubic chunks on reddit ("what's the difference between chunk sections and cubic chunks?").

EDIT: To be clear, these ALWAYS load for me eventually, but often are the last chunks loaded.

Yup most terrain is not rendering until within 30 m or so, or force with F3+A as John indicated. My only difference than the original posted pics is that mine are giant areas and not just strips.

These problems didn't happen very much for me in 1.7.x and my Average Frame Rate was always around 60 but ever since the 1.8 snapshots my Average Frame Rate is now around 40 - 50 Frames except in certain areas then its around 70 - 100 Frames.

when 1.8 comes out I hope Optifine will be updated soon after.

UPDATE: Downloading Java 8 doesn't help Chunk Loading all the way but it helped me a lot when I updated my version. however... its not available on java.com yet but you can get it from the Oracle directly using the link below

I can confirm that this is a problem in 14w20b. I'll attach a screenshot.

FYI, I'm using the "Fast" graphics settings

More pictures, after walking for about 200 to 300 blocks, through an area I've explored before (but not this session)

Quick question for John (and others).

Are you using Advanced OpenGL? I was thinking about it on my work today, I tinkered with this setting around the same time I noticed the unloaded chunks. I'll test tonight with that setting off.

For me it happens with and without Advanced openGL on, and I have a fast computer.

I can't reproduce the problem with Advanced OpenGL off. I have to keep Graphics on "Fast," because this is an older laptop.

I am also experiencing chunk rendering issues in 14w21b.

After looking at some of the above comments I tried turning Advanced OpenGL off, and the issue stops!

System Specs: Ubuntu Linux (64bit) Java version "1.7.0_55" OpenJDK Runtime Environment

Turning off Advanced OpenGL is a temporary fix for this bug! (For me at least)

I've never used OpenGL and I get it. Maybe worth mentioning that I'm using the 32bit version of Java. I know some bugs don't show up on the 64bit one.

@unknown: Surely does your Minecraft use OpenGL, but maybe not Advanced OpenGL.
This ticket was created with a 64bit environment:Operating System: Windows 8.1 (amd64) version 6.3, Java Version: 1.7.0_55

Seen this in the last two or three snapshots (14w19-14w21). In single player I get missing strips or worse. In multiplayer I can only walk 30m and chunks stops loading. Nearly unplayable unless turning off Advanced OpenGL.
