Texture reuse between recompiled kernels is incorrect

[robertleeplummerjr]

What is wrong?

Kernels that are recompiled that share the same recycled output texture doesn't update correctly.

Where does it happen?

General use, just after recompile and deletion of a texture.

How do we replicate the issue?

const { GPU } = require('./src');
const gpu = new GPU({ mode: 'gpu' });

const kernel = gpu.createKernel(function (value) {
  return value[this.thread.x] + 1;
}, { output: [1], pipeline: true, immutable: true });

const result1 = kernel([1]);
console.log(result1.toArray());
const result2 = kernel(result1);
result1.delete();
console.log(result2.toArray());
result2.delete();
const result3 = kernel([3]);
console.log(result3.toArray()); // 
const result4 = kernel(result3);
result3.delete();
console.log(result4.toArray());

Outputs:

Float32Array [ 2 ]
Float32Array [ 3 ]
Float32Array [ 3 ]
Float32Array [ 5 ]

How important is this (1-5)?

4

Expected behavior (i.e. solution)

Should output:

Float32Array [ 2 ]
Float32Array [ 3 ]
Float32Array [ 4 ]
Float32Array [ 5 ]
