# Known Sky-Rendering Glitches

A bug tracker for the firmament. Every ticket logs a spot where the backdrop supposedly shows its seams: a flickering horizon, clouds that pop in, a moon reused across every time zone. Assignee on all of them, naturally, is Big Sky.

Each ticket runs in three parts: what the "witness" reported, the status we stamped on it, and then, one tap away, **what is actually happening**, which is always more elegant than a bug.

## GLITCH-001 · Z-fighting at the horizon (sunsets)

Won't Fix

*Report:* at dusk the sky can't decide on a color, so two textures fight over the same pixels: orange, pink, a bruised violet, all flickering as the sun clips through the floor of the world.

Big Sky Severity: gorgeous

**What's actually happening**

At sunset the light travels a much longer path through the atmosphere, so more of the short (blue) wavelengths scatter away and the reds and oranges reach your eye. It's called Rayleigh scattering, and it's why noon is blue and dusk is red. No texture fight, just air doing physics.

## GLITCH-014 · Cloud pop-in

Working as Designed

*Report:* clouds "appear" as you watch, and the far ones fade into a haze at the horizon. Classic render distance. The world is buffering.

Big Sky

**What's actually happening**

Clouds form when moist air rises, cools, and its water vapor condenses past the dew point onto tiny particles. They genuinely wink into being. The horizon haze is just a lot of atmosphere stacked edge-on between you and the distance. Depth, not a draw call.

## GLITCH-032 · The moon, reused across every time zone

Duplicate

*Report:* one moon asset, instanced globally. Everyone sees the same face, the same craters, the same tidy circle. Suspiciously efficient.

Big Sky (there is only one)

**What's actually happening**

There *is* only one Moon, and it's tidally locked to Earth, so the same side always faces us. It's also far enough away that everyone on the night side sees essentially the same view at once. One object, one face, real orbit.

## GLITCH-047 · Lens flare with no lens

Cannot Reproduce

*Report:* look near the sun and you get streaks, rings, and the odd bright spot beside it. Lens flare. But the naked eye has no lens coating, so who's compositing this?

Big Sky (please stop staring at the sun)

**What's actually happening**

Your eye very much has a lens, and light scatters and diffracts inside it. Those bright spots flanking the sun can be sun dogs, sunlight refracting through hexagonal ice crystals in high cirrus clouds at about 22 degrees. Optics, not post-processing. (And really, don't stare at the sun.)

## GLITCH-063 · Color banding on the ramp (rainbows)

Won't Fix

*Report:* after rain the sky shows a perfect gradient in fixed bands, same order every time. That's an 8-bit color ramp if we've ever seen one.

Big Sky Severity: delightful

**What's actually happening**

Each raindrop refracts sunlight, splits it by wavelength, bounces it off the back of the drop, and sends it out at about 42 degrees. Millions of drops do this at once and you see an arc, always in the same spectral order because that's the order light disperses. The "banding" is the actual spectrum.

## GLITCH-088 · Screen tearing during a solar eclipse

Scheduled

*Report:* occasionally the sun is briefly overwritten by a black disc. Total draw failure. Somebody shipped on a Friday.

Big Sky (see the [maintenance memo](https://theskyisnotreal.com/evidence/memo))

**What's actually happening**

The Moon passes directly between the Earth and the Sun and its shadow falls on you. It's predictable centuries in advance because it's just orbital geometry. Not a crash, a clockwork coincidence of sizes and distances that happens to be spectacular.

## The pattern

Every "glitch" is a real phenomenon with a real, testable explanation, which is exactly the joke: a confident bug report can make wonder look like a defect. Read the [leaked maintenance memo](https://theskyisnotreal.com/evidence/memo) next, or [run the Deception Detector](https://theskyisnotreal.com/#scan) on your own sky. Then go read about Rayleigh scattering for real. The sky is not a render. It's better than one.
