World turns completely black when having night vision, and being in the void or having blindness

I can confirm this happening in 1.8.1

Confirmed for 1.8.2-pre1.

The way night vision interacts with fog leads me to believe that the bug is caused by the "void box" around the player, which is black. The void box is the black area around the player that hides the skybox while in the void.

Confirmed in 1.8.4

This happens to me without a night-vision potion.

Confirmed for 1.9-pre1. The beacon beam and glowing effect caused by spectral arrows are still visible.

Confirmed for 16w38a

@unknown No, if you close yourself in with e.g. quartz blocks, you can still see something although there is no light. And even if it was normal, the sudden change of brightness at a certain height definitely isn't.

Appears to be fixed in 17w06a.

In 17w06a with nighvision hand is not visible, without it it is visible, hud included.
GTX 1060, Windows 10 in case it matters

If you put nighvision then drink milk, effect correctly updates to being black. If you go out and then down again it will not be black again

Not AMD specific, had it with Intel, too.

MC-10480 appears to be caused by the same issue, although that was resolved as intended for some reason. Both seem to only occur on non-NVIDIA graphics cards as described in this report.

Confirmed in 17w18a

Ticket is yours now, @unknown

@unknown Thanks for the reassignment. Would it be possible to get MC-10480 reopened or have the devs look at it again, since it seems to have the same behavior as this bug?

@unknown, MC-10480 is already marked to be reviewed.

Ok thanks.

I believe it also works if you use potions

Confired 1.15.1

I can reproduce the bug with my Radeon RX550 in version 1.15.2 and 20w13b.

Confirmed on 1.15.2 and a NVIDIA graphics card (gtx 960)
for greatly weakened underwater blindness

Minecraft 1.16.1

Blindness effect greatly weakens while underwater

NVIDIA GeForce GTX 1650 graphics card

I've recently found that my computer has this bug, (Night Vision / Underwater + Blindness / Void turning everything black) but only when on its power saving mode. (Likely due to the graphics card not being used when saving power)

This, as well as the features in 20w28a allowing me to change the fog color for custom biomes, has allowed me to find some things that should help to fix this bug (As well as the one in MC-165208, which is why I'm putting this comment there too)

Basically, Night Vision (and being underwater) divides the fog color's RGB values (assuming they're 0 - 1) by the largest value out of R, G, or B; effectively making the fog color as bright as it can be. This works fine for most colors, but if the fog color is exactly (0, 0, 0) then the largest value in the color is 0, resulting in the color being (0 / 0, 0 / 0, 0 / 0). This calculation is why the glitch only happens on some graphics cards, as while some of them (I believe the NVIDIA ones) will set the fog color to (0, 0, 0) others may return a NaN value, resulting in (NaN, NaN, NaN). The NaN values echo through the shaders and rendering code, resulting in a ton of stuff rendering completely black.

The reason why the glitch occurs when in the void or under the Blindness effect is because both make your fog color completely black. The same effect can be achieved by making a custom biome where the fog color is 0, also showing this. A potential fix for the bug may be to add a special case in the fog rendering code to skip any fog brightening effects if the fog color is completely black.

Another thing I've noticed: This bug report appears to contain two mostly unrelated bugs, those being the Night Vision rendering bug and the weakened Blindness effect while underwater. As for the second bug, I believe it to be caused by both Blindness and water changing your fog distance; the slightly reduced fog distance of water appears to override the greatly reduced fog distance of the Blindness effect. I believe this too could be fixed if Mojang adds a special case to the code reducing the fog distance while underwater where if the fog distance is already less than the underwater fog distance then to not change the fog distance.

@unknown: The behavior while underwater is the same as with Night Vision (at least for me); having blindness while underwater turns the screen black.

I just tested it for myself, and it seems like you're right; being underwater seems to brighten the fog just like Night Vision does, leading to all terrain and text rendering completely black when under Blindness / in a custom biome with black fog / in the void (I didn't test the void though since you can't put water there)

I also found why I, and a few others in the comments, may have been a bit confused regarding which issues this report is tracking; MC-167763, a report tracking the unrelated 'weakened underwater blindness' bug (Easier to see when using a graphics card not affected by the Night Vision bug) was marked as a duplicate of this one, leading to this report about Night Vision / Underwater + Blindness / Void turning everything black containing a lot of comments about the other bug.

I'll update the comments I made earlier to reflect the new information. Also, I think MC-167763 should be reopened to avoid future confusion, as it is a different bug than MC-4647.

Thanks @unknown, I have reopened MC-167763 and confirmed it myself.

Still a problem in 20w46a. 

I use NVIDIA card so I can't reproduce

In 20w51a, Night Vision + The Void turns the world black (basically a negative brightness sky).

In 21w07a all text and HUD goes black below -64.

That's MC-165208.

Can confirm with void and blindness in 21w08a and 21w08b

can confirm for 21w11a
