White dots/pixel glitches on blocks with specific texture atlases

Bug Description

I found a similar bug to the one AxolotlAccount had, but with some different mods: Version 1.20.1 Forge

Citadel 2.5.3 - Curios 5.7.0 - embeddium 0.3.2 - Farmers Delight 1.2.4 - Fruitful Fun 7.1.6 - Kiwi 11.5.3 - L_Ender_Cataclysm 1.90 - Lychee 5.1.9 - touhoulittlemaid 1.1.7 - Zeta 1.0.13 - Quark 4.0.435

Yes, ALL of them together. Remove any mod and the white dots dissapear, I tried removing Fruitful and L_ender and leaving only it's dependencies but you need those also or the bug doesn't happen.

An example picture, but moving you see it more clearly.

In this case i removed quark, but removing any of the mods above would fix it

Model Gap Fix also causes the same issue, and when i removed it and the issue persisted it was so strange. No clue why it also happens only when you have all of this mods together. I hope this can help.

Reproduction Steps

Illuminate a cave or similar closed place with a torch and you'll see this white dots in darker places.

I have had the same issue with Rubidium a few months ago. Here's the unresolved issue on Rubidium's github.

I still encounter the issue with Embedium. I've tried everything related to anti-aliasing settings to no avail. I have no idea what it could be related to. I hope the dev of embedium can find the root, because it's really distracting.

As this may be a very fringe case related to hardware, I'm playing on a 1440p 240hz monitor with a 3080.

Bumping so I can remember to test this out when I get home

So... did you test it out?

This is happening to me too, at least I believe it is the same issue. (Open full pic to see it clearly)

I don't know if the leaves glitching at the end is from the same issue but yeah, pretty unplayable.

(I believe the video sharing service I used has hidden the effect after processing, it's way harder to see)

For those experiencing this issue, the current recommendation while we work on the fix is to disable "Compact Vertex Format" under the "Performance" tab in settings. If you are using the "Model Gap Fix" mod, you will also need to tweak its config or remove it, otherwise this fix will not work.

Note: the precision issue also appears to cause torch textures to overflow slightly, see #199.
