Here is a modified version of the PS3 menu shader I've updated to be compatible with the latest developer instructions.
#version 450
layout(location = 0) in vec2 qt_TexCoord0;
layout(location = 0) out vec4 fragColor;
layout(std140, binding = 0) uniform buf {
mat4 qt_Matrix;
float qt_Opacity;
float iTime;
float iTimeDelta;
float iFrameRate;
float iSampleRate;
int iFrame;
vec4 iDate;
vec4 iMouse;
vec3 iResolution;
float iChannelTime[4];
vec3 iChannelResolution[4];
} ubuf;
layout(binding = 1) uniform sampler2D iChannel0;
layout(binding = 1) uniform sampler2D iChannel1;
layout(binding = 1) uniform sampler2D iChannel2;
layout(binding = 1) uniform sampler2D iChannel3;
vec2 fragCoord = vec2(qt_TexCoord0.x, 1.0 - qt_TexCoord0.y) * ubuf.iResolution.xy;
float iTime = ubuf.iTime;
vec3 iResolution = ubuf.iResolution;

const float speed = 0.4;
const float widthFactor = 2.0;
vec3 calcSine(vec2 uv,
float frequency, float amplitude, float shift, float offset,
vec3 color, float width, float exponent, bool dir)
{
float angle = iTime * speed * frequency + (shift + uv.x) * 0.75;
float y = sin(angle) * amplitude + offset;
float clampY = clamp(0.0,y,y);
float diffY = y - uv.y;
float dsqr = distance(y,uv.y);

if(dir && diffY > 0.0)
{
dsqr = dsqr * 4.0;
}
else if(!dir && diffY < 0.0)
{
dsqr = dsqr * 4.0;
}
scale = pow(smoothstep(width * widthFactor, 0.0, dsqr), exponent);
return min(color * scale, color);
}
void mainImage( out vec4 fragColor, in vec2 fragCoord )
{
vec2 uv = fragCoord.xy / iResolution.xy;
vec3 color = vec3(0.0);
float t1 = (sin(iTime/20.0) / 3.14) + 0.2;
float t2 = (sin(iTime/10.0) / 3.14) + 0.2;

color += calcSine(uv, 0.40, 0.15, 0.0, 0.5, vec3(0.5, 0.5, 0.5), 0.1, 17.0,false);
color += calcSine(uv, 0.60, 0.15, 0.0, 0.5, vec3(0.5, 0.5, 0.5), 0.05, 23.0,false);
color += calcSine(uv, 0.26, 0.07, 0.0, 0.3, vec3(0.5, 0.5, 0.5), 0.1, 17.0,true);
color += calcSine(uv, 0.46, 0.07, 0.0, 0.3, vec3(0.5, 0.5, 0.5), 0.05, 23.0,true);
color += calcSine(uv, 0.58, 0.05, 0.0, 0.3, vec3(0.5, 0.5, 0.5), 0.2, 15.0,true);
color.x += (0.9-uv.y);
color.y += (0.7176-uv.y);
color.z += (0.77-uv.y);
fragColor = vec4(color,1.0);
}
void main() {
vec4 color = vec4(0.0);
mainImage(color, fragCoord);
fragColor = color;
}As you can see, I've modified the color x, y, z to fixed values. Here is my expected look from shadertoy:
I originally compiled this file with the same name using the original colors, without modification. The original changes the red and green channel values only, based on the t1 and t2 values.
I chose another shader in wallpaper selector, then performed this command:

'jb-test.frag.qsb' -> '/home/jbanasik/.local/share/plasma/wallpapers/online.knowmad.shaderwallpaper/contents/ui/Shaders6/jb-test.frag.qsb'
I reselect the jb-test.frag.qsb, and I get the same exact results. I copied my file, adding a 2 to the name, and reran this command a couple of times just to be sure before selecting the shader.
❯ rm -v jb-test2.frag.qsb; rm -v /home/jbanasik/.local/share/plasma/wallpapers/online.knowmad.shaderwallpaper/contents/ui/Shaders6/jb-test2.frag.qsb; qsb --glsl "100 es,120,150" --hlsl 50 --msl 12 -o jb-test2.frag.qsb jb-test2.frag && cp -v jb-test2.frag.qsb /home/jbanasik/.local/share/plasma/wallpapers/online.knowmad.shaderwallpaper/contents/ui/Shaders6/
removed 'jb-test2.frag.qsb'
removed '/home/jbanasik/.local/share/plasma/wallpapers/online.knowmad.shaderwallpaper/contents/ui/Shaders6/jb-test2.frag.qsb'
'jb-test2.frag.qsb' -> '/home/jbanasik/.local/share/plasma/wallpapers/online.knowmad.shaderwallpaper/contents/ui/Shaders6/jb-test2.frag.qsb'
It is now correct. The files are identical, but one works and the other doesn't:

What mechanism is leading to this being cached and how can I avoid it for rapid development?
Thanks!
