Confirmed.

This may be an issue related to the Intel HD graphics. Is the driver up to date?

migrated 2013-01-30T13:35:49Z

I think it may be a compatibility issue between the Minecraft applet and Apple's Java 6. I can confirm this too. This also doesn't happen on any of the Windows computers I have tested. It seems to be an Apple only bug.

Added some more screenshots with the debug screen open to show F:.

You have a modded minecraft. Can anyone else with this issue please force a crash by pressing F3 + C for 10 seconds while ingame and attach the crash report here.

Attached manual crash report, requested by Anon Ymus

I have this same lighting error. It didn't happen before 1.4.6/1.4.7, could it have anything to do with any of the bug fixes?

CubeTheThird 2013-02-06T04:06:17Z

According to the crash report, you are using an old version of openGL. Are you able to update your graphics drivers?

migrated 2013-02-06T05:16:27Z

You haven't ever worked on a Mac, have you? Graphics drivers come only with System Update, which I have most recent. Besides, Apple has their own modified version of OGL. From what I remember (not sure though); 2.1 APPLE-8.6.22 is a mix of OGL 3 and OGL 2, with some custom Apple modifications.

Force Updated minecraft, used an un-modded version of Minecraft 1.4.7, force crashed and added a crash report.

CubeTheThird 2013-02-06T20:44:20Z

Something you can try, though I am not expecting much difference, is updating your LWJGL version (instructions here).

migrated 2013-02-06T23:11:05Z

Updated LWJGL to the current version. Big performance increases, up to +20FPS than before, but the bug is still there.

CubeTheThird 2013-02-06T23:23:30Z

Well at least it did something.

CubeTheThird 2013-09-26T04:38:10Z

Is this still a concern in the current Minecraft version 1.6.4 / Launcher version 1.2.5 ? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.

migrated 2013-09-26T10:49:20Z

This bug still exists in Minecraft 1.6.4/13w38c.

migrated 2013-09-28T03:58:02Z

I don't know if this could help, but I found a mod that solves this problem specifically, including all of the problems detailed here. (Chest, hand and mobs lighting glitches). http://www.minecraftforum.net/topic/1547522-162-164-minecraftlfm-fixes-colored-signs-entity-rendering-and-much-more-4000-downloads/

galaxy_2alex 2014-01-21T22:01:22Z

Is this still a concern in the current Minecraft version 1.7.4 / Launcher version 1.3.8 or later? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.
