[MC-40420] MAJOR texture/rendering glitch

When I join one of my worlds or a multiplayer server, everything, literally everything starts going crazy. Textures become inverted, text becomes unreadable, all in the midst of a lot of flashing. Similar bug reports I've seen show the glitch only happening when a decoration block is held (unlike this glitch) or mipmap is on (unlike this glitch because it affects 1.6.4). It is very hard to explain in words, ~~so I will take and add screenshots ASAP.~~ Screenshots provided.

Please force a crash by pressing F3 + C for 10 seconds while in-game and attach the crash report ([minecraft|http://hopper.minecraft.net/help/finding-minecraft-data-folder]/crash-reports/crash-<DATE>-client.txt) here.

Here is a screenshot taken right before a crash log, also attached.

Server brand: craftbukkit - I don't believe this has an effect, but can you please reproduce this in vanilla Minecraft?

Also...
Your Java version is out of date! Please update your Java to the latest version (1.7.0_45): http://www.java.com/en/download/.

When using a 32-bit browser on a 64-bit operating system the automatic version detection will only show the 32-bit version of Java, the 64-bit version needs to be downloaded manually: http://www.java.com/en/download/manual.jsp.

Please report if the issue persists with the latest Java version.

After I downloaded that version of Java, I checked the launcher's development notes tab and it showed this:

[16:36:01 INFO]: System.getProperty('java.version') == '1.6.0_65'

I believe this line means Minecraft thinks the java version is still 1.6, even though I ran the .dmg file for the Java installation. To make sure the Java version is 1.6, I used the Terminal command "java -version" and got this:

java version "1.6.0_65"

On the other hand, when I downloaded the .dmg file, the webpage gave me this:

Chrome does not support Java 7. Java 7 runs only on 64-bit browsers and Chrome is a 32-bit browser.
If you download Java 7, you will not be able to run Java content in Chrome and will need to use a 64-bit browser (such as Safari or Firefox) to run Java content within a browser. Additionally, installing Java 7 will disable the ability to use Apple Java 6 on your system.

Was it a bad idea to download Java 7, or am I overreacting to the message?

Don't worry about it unless you use a website that requires Java. I actually disable their plugins for browsers to prevent virus infections.

Java VM Version: Java HotSpot(TM) 64-Bit Server VM (mixed mode), Apple Inc.

Make sure you are updating the 64 bit version, you've probably only updated the 32 bit version.

I wouldn't worry too much about the java version, as Apple only fully supports 1.6 u 65 which they release themselves.

JB 2013-11-20T00:25:34Z

Talven81, the name of the .dmg file had "x64" at the end, so it should be the 64 bit version, but I will take CubeTheThird's advice and not worry about the Java version. I will now upload a screenshot of this glitch in vanilla, as Talven81 requested. I just realized the first screenshot didn't show the flashing very well, so hopefully the second screenshot will.

JB 2013-11-20T00:45:07Z

Here is another screenshot and and another crash report.

CubeTheThird 2013-11-20T01:37:09Z

I'm not sure I can see any issue in the second screenshot.

The not loaded chunk in the middle, but that's MC-129

JB 2013-11-20T20:18:28Z

What is shown in the screenshots is a bad example of the "flashing" because it is obviously impossible to show flashing with a still image. I might try using QuickTime's video screenshot feature to capture the flashing instead of Minecraft's screenshots to give you all a better idea of what the issue is.

JB 2013-11-20T20:41:00Z

Here is the glitch on video. Sorry it's so short. The file size limit sucks.

CubeTheThird 2013-11-20T22:59:44Z

It looks as though the chunks are constantly reloading.

JB 2013-11-20T23:23:17Z

On servers it gets much worse (see screenshot and first sentence of description), but I don't know if that is a glitch with Bukkit or the Minecraft server software. The only way to test would be to join a vanilla server, but I don't know any.

CubeTheThird 2013-11-21T01:22:19Z

A quick google search reveals: http://minecraft-server-list.com/sort/Vanilla/ . Join a server, force a crash report on it (assuming the issue occurs).

JB 2013-11-21T23:55:05Z

Here is a crash report on a vanilla server. Some issues that happen in Bukkit do exist, but they take time to occur and aren't as serious.

CubeTheThird 2013-11-30T18:21:12Z

Does this still occur in the current snapshot 13w48b with launcher 1.3.4 ?

JB 2013-12-02T23:25:42Z

Unfortunately, the glitch does affect snapshot 13w48b.

Ezekiel 2014-01-17T16:59:22Z

Is this still a concern in the latest Minecraft version 14w03b? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.

JB 2014-01-18T14:13:24Z

The glitch does not affect singleplayer worlds or vanilla servers anymore (Yay!), but Bukkit hasn't updated so I don't know if it affects Bukkit servers.
