I have been having a very strange issue with the newer versions of Forge (1.7.2 versions). These issues take place both in compiled Minecraft and decompiled Minecraft (in the workspace that ForgeGradle sets up).

 

Basically, my issue is that the world renders with the underground visible and textures start clipping randomly. This does not take place in Vanilla Minecraft where Forge is not installed. If pictures help to visualise the issue I will be happy to provide some.

 

I have checked these forums for similar bug reports but failed to find any. I also checked the GitHub repository for any issues that might be relevant but failed to find any there as well.

 

Forge 1025 works fine, but would like to upgrade to the later versions of Forge to take advantage of the new bugfixes and improvements whilst modding.

 

I have changed every setting on my graphics card that I could find, but upgrading the drivers is out of the question; I attempted to do such a thing upon upgrade to Windows 8, but found that the computer manufacturer (Sony) has requested a special driver set from ATI which when looking on the ATI website for driver updates constantly redirects me back to the Sony website, which indicates that I have the "latest" driver set.

 

The only thing in my log that seems out of place is the repeated mention of "1280: Invalid Enum". I have a log, which I created in the development environment because I assume that the logging output may be more verbose here (If I am wrong about this and I should have created the log from the launcher then I would be happy to provide a log from there ASAP).

(a small note, this development environment is untouched and no changes have been made to it).

 

Forge version: 10.12.0.1055

 

Sorry if I made any mistakes, and thanks in advance for any help.

1) When its a graphical issue, ALWAYS go with screenshots. it's far easier to see what you see then it is to try an imagine it.

2) Dev env, or Runtime has pretty much the same logging if you grab the right log file, which is located in .minecraft/logs

3) Invalid enum may cause this as that is a error in the GL stack, it could be that your graphics card does not support some call we are doing. However we shouldn't be adding anything beyond what vanilla already does. So i'm not sure.

4) It would be nice if you could track down the error to a specific build number instead of a range of 30 builds. Simply install multiple versions of forge and then use the launcher's edit profile page to select which version to use.

I find that spltting the range in half and then seeing if that still has the issue and repeating lets me find the issued build quickly. {So you'd try 1040, if it still errors try 1032 if not try 1047, rinse repeat till you have one}

 

Anyways, we don't do much more rendering wise then the vanilla minecraft does, and it works for what appears to be everyone but you So we'll need your help to track it down. Then again, could be your drivers like you said, exp on windows 8. Which always likes to be a pain to rendering.

Thank you While I test out the builds I have a screenshot here.

 

I'll get back with the build number ASAP.

Allright, I have got the build numbers:

 

Forge 10.12.0.1040 was the last version to work properly and Forge 10.12.0.1041 was the first version to give me graphical issues.

 

I hope this helps

 

Edit: after looking at the changelog, it appears that something that seems to be rendering-related was in-fact changed:

Build 1041:

ohai.iChun: Fixes stencil bits not existing in Minecraft's framebuffer causing stencil test to not work.

Ah Figures ichun broke it, I'll have look into it. I'm not the best when it comes to rendering so if anyone knows OGL it'd be useful to step forward

But i'll see what I can do here tonight when I have time.

 

https://github.com/MinecraftForge/MinecraftForge/pull/1029 May of fixed it, seems ichun mixed GL 3.0 with 2.1 calls.

Try latest Forge to test.

Thanks ever so much!

 

I am unable to convey how grateful I am for the help

It appears that it was too early to count the proverbial chickens. I'm not sure if this is a different issue, but now whenever I hold an item the screen goes weird. E.g.

 

I'll have another look to see if this is the case in earlier builds.

 

Edit: It just occurred to me, I remember having this issue with one of the first Minecraft 1.7 vanilla versions. I removed Forge entirely. It seems to only be occurring when I hold an item such as a tripwire hook or a flower. Is there a way of reporting bugs to Mojang that I should know about?

 

Edit 2: scratch that. It appears by resetting my graphics card to default settings the bug with the items is gone. Sorry Again, I can't express how grateful I am for the original fix.

The original fix is gunna need to be reverted as it's killing some peoples games on certian hardware.

Will need to look more into this.

I get the black display, but the sound works.

I already have the latest Forge:  1057.

Here is the Forge diagnostic information showing the framebuffer rendering problems: https://gist.github.com/anonymous/caec8da415d81fc32b48

 

I tried installing the latest driver from Intel, but it did not help.

 

Here is the DxDiag.txtx output:  https://gist.github.com/anonymous/9d60bd1dc3fba7e9215a

 

I have tested with Vanilla 1.4.2, 1.4.4 and 1.4.5 and they all work fine.  No rendering problems.

 

 

Oh dear. I hope I haven't caused too much of an issue. I wish I could help more, but I'm not too good with OpenGL. If you need any fixes for this problem tested I'm always happy to help when I have time

I can confirm that this rendering problem (framebuffer errors) is also breaking Forge 1057 on my Apple laptop running OS/X Mavericks.

Intel HD Graphics 4000

NVIDIA GeForce GT 650M with 1GB of GDDR5 memory and automatic graphics switching

I tried disabling the Intel HD 4000 card on my Macbook Pro.  I still got the framebuffer errors.  So the error is also hitting the NVIDIA GeForce GT 650M with 1GB of GDDR5 memory.

I've just setup my Forge 1056 workspace and noticed the same weird world rendering error, also the gl error during pre startup (1080 invalid enum).

I switched back to the recommended version (forge 1024) and voila: bugs are gone
