Since about summer 2022, there have been increasing reports of issues where the game's graphics would glitch out when holding items or looking at certain things (terrain or the entire screen becomes solid color, incorrect textures being bound, etc.).

Strictly speaking, this isn't an issue to NTM in itself since it has been reported on instances running different mods or no mods at all. The issue is likely caused by a faulty update that has been rolled out to PCs with Intel UHD series integrated GPUs, although there have been a few reports of the same thing happening with certain dedicated NVIDIA or integrated AMD cards.

Nevertheless, there are a few approaches as to how this issue could be fixed:

• Downgrading the graphics drivers to an earlier version, probably one from early 2022 (I don't know the exact version numbers for the UHD drivers, but exact versions shouldn't really matter anyway). This method seems to be the most effective, but be warned that messing with your drivers may have some side effects, so perhaps try this option when the other ones don't work.
• Switching GPU, often times PCs that have dedicated GPUs that should work correctly also come with integrated GPUs running alongside them, depending on the brand and driver, it's possible to define what GPU the game runs on. For NVIDIA cards, this can usually be done in the NVIDIA control panel in the tab "Manage 3D settings".
• Using a different launcher, it's unclear how that would fix a rendering issue (possibly due to different graphics libraries being used), but there has been one report where simply switching the launcher seemingly fixed it.
• Using Neodymium, a performance mod that changes the way chunk rendering works which has the side effect of also fixing this issue. Due to the change in rendering, Neodymium might have some incompatibilities with certain other graphics mods, so be sure to check out the project's readme before using it.

A cheer for auto-updating drivers! Hip hip hooray!

well I need an alternative

(closing because it's not so much of a fixable issue on my side that can be completed but rather an announcement)

oh ok

Commenting here because this shows up in Google searches.

https://www.planetminecraft.com/blog/how-to-fix-1-7-10-graphic-bug/ suggests using Neodymium. The mod says it "reimplements chunk rendering in Minecraft 1.7.10 using modern OpenGL. This should improve performance on most hardware."
