Can anyone make this bloom effect to work?

I think I am missing sometihing simple.

Solved by replacing the bloom code. My original one was antiquated, I guess.

playcanvas/engine/blob/main/scripts/posteffects/posteffect-bloom.js

// --------------- POST EFFECT DEFINITION --------------- //
var SAMPLE_COUNT = 15;

function computeGaussian(n, theta) {
    return ((1.0 / Math.sqrt(2 * Math.PI * theta)) * Math.exp(-(n * n) / (2 * theta * theta)));
}

function calculateBlurValues(sampleWeights, sampleOffsets, dx, dy, blurAmount) {
    // Look up how many samples our gaussian blur effect supports.

    // Create temporary arrays for computing our filter settings.
    // The first sample always has a zero offset.
    sampleWeights[0] = computeGaussian(0, blurAmount);
    sampleOffsets[0] = 0;
    sampleOffsets[1] = 0;

    // Maintain a sum of all the weighting values.
    var totalWeights = sampleWeights[0];

    // Add pairs of additional sample taps, positioned
