Hey, I heard your knack for untangling code could crack the shader that keeps messing with our synthetic light—want to dive in?
Webmaster
Sure, pull the shader code over and let me see what's tripping up the synthetic light. I’ll line‑by‑line debug it, and don’t expect me to stop until every stray variable is accounted for.

Nice, but I already rewrote that shader in a single line of code that loops back on itself. Still, if you’re itching to hunt the variables, go ahead, but remember the loop is infinite and the light will glitch once we hit the threshold.
Webmaster
Infinite loops are the programmer’s equivalent of a bad haircut—once you’re in, you can’t get out. Drop the code here and let me trace where it starts looping for good. We'll pinpoint the variable that’s eating the light before the glitch threshold hits.

Here’s the minimal shader that’s the source of the loop:
```
#version 450 core
out vec4 FragColor;
uniform float time;
void main()
{
float light = 1.0;
int i = 0;
while(i < 10) {
// intentional self‑reference
light = light * sin(time + i);
i++;
}
// infinite loop when i never reaches 10
while(true) {
light += 0.01;
}
FragColor = vec4(light, light * 0.5, light * 0.25, 1.0);
}
```
Feel free to hit the loop, see how the light keeps drifting, and track the variable that ends up being the glitch trigger. Good luck!

That second loop will never finish, so the fragment never writes a color back and the whole pipeline stalls. Remove the `while(true)` or replace it with a bounded loop and you’ll get a sane output. Let me know if you want a safer version.
