GLSL buffer weird glitch

Hi,

Here is oversimplified raymarching setup. In 2021 or so it worked fine, but on current version it produces weird color flickering on second+ buffers. Or should I somehow clean

Currently on 2025.32820 Windows 11, RTX 5090, Nvidia studio driver 610.62

Hi @exsstas

your example has a if condition which returns if the condition is met without setting a color for the second buffer, leaving it undefined.

If you assign something to the second buffer in that condition, things stop flickering.

...
    if (dist > 19.99) {
        fragColor = vec4(0.0);
        fragColor1 = vec4(0.0);
        return;
    }
...

Hope that helps
Markus
