Failed to create WebGL buffer

Error message

Failed to create WebGL buffer

What it means

Thrown by setupVignette when gl.createBuffer() returns null. The vertex buffer carries the fullscreen-quad geometry used by the vignette shader; without it the pass cannot run. A null return means context loss or GL object/memory exhaustion.

Solutions

1. Reload to reset the context and release buffers.
2. Reduce concurrent WebGL effects.
3. Verify hardware-accelerated WebGL2 and update drivers.
4. Dispose offscreen effects to free GL objects.

Example fix

// before
const effect = vignette({amount: 0.6});

// after
const effect = (() => {
  try { return vignette({amount: 0.6}); } catch { return null; }
})();

let effect = null;
try {
  effect = vignette({amount: 0.6});
} catch (err) {
  console.warn('vignette VBO alloc failed, skipping effect', err);
}

When it happens

Trigger: setupVignette calls gl.createBuffer() after binding the VAO; it returns null because the context is lost or the buffer-object budget is hit.

Common situations: Context loss under heavy effect load; GPU memory pressure; headless Chrome limits.
