After creating filter with lut texture i see a weird outline under the dots

[SRD]

vertShader:string = `

// https://github.com/pixijs/pixi.js/issues/6436 * this one!!!

//pixi.js/packages/core/src/fragments/default.vert

attribute vec2 aVertexPosition;

attribute vec2 aTextureCoord;

uniform mat3 projectionMatrix;

varying vec2 vTextureCoord;

void main(void)

{

gl_Position = vec4((projectionMatrix * vec3(aVertexPosition, 1.0)).xy, 1.0, 1.0);

vTextureCoord = aTextureCoord;

}

`;

fragShader:string = `

varying vec2 vTextureCoord;

uniform sampler2D uSampler;

uniform sampler2D u_lut;

 

void main(void)

{

vec4 pixelColor = texture2D(uSampler, vTextureCoord);

gl_FragColor = texture2D(u_lut, vec2(pixelColor.r, 0.0));

}

`;

 

const filter = new PIXI.Filter(this.vertShader, this.fragShader, this.uniforms);

container.filters = [filter];

Do you use alpha channel there? f so, you have to divide by alpha and then multiply ahain.
