Failed to create WebGL buffer

Error message

Failed to create WebGL buffer

What it means

During zoomBlur setup, `gl.createBuffer()` returned `null`, meaning the WebGL2 context could not allocate a vertex buffer object for the fullscreen-quad geometry. This is a resource-exhaustion or context-loss condition, not a user parameter issue.

Solutions

1. Reduce the number of concurrent WebGL effects.
2. Handle context loss and recreate effect state.
3. Update GPU drivers.
4. Ensure effect cleanup (`cleanupZoomBlur`) is called to free GL objects.

try {
  zoomBlur({ amount: 40 });
} catch (err) {
  if (err instanceof Error && err.message.includes('WebGL buffer')) {
    console.error('VBO creation failed:', err.message);
  } else {
    throw err;
  }
}

When it happens

Trigger: WebGL2 context lost, GPU buffer/object limit reached from many concurrent effects, or a degraded driver state.

Common situations: Compositions stacking many WebGL2 effects, context loss after GPU reset, rendering on hardware with tight WebGL2 object limits, or long-running sessions that leak GL objects.
