Failed to create WebGL buffer

Error message

Failed to create WebGL buffer

What it means

Thrown inside `lightLeak`'s setup when `gl.createBuffer()` returns `null`. The vertex buffer holding the fullscreen-quad data could not be allocated — context loss or GPU buffer memory/object-slot exhaustion.

Solutions

  1. Reduce concurrency and dispose unused GL buffers.
  2. Handle context loss and recreate the effect.
  3. Restart the GPU/Chrome process to reclaim leaked buffer objects.
  4. Render with adequate video memory.
Defensive patterns

Strategy: try-catch

Try / catch

try {
  lightLeak({...})(...);
} catch (err) {
  if (/Failed to create WebGL buffer/.test(String(err))) {
    console.warn('lightLeak() VBO unavailable', err);
  } else {
    throw err;
  }
}

Prevention

When it happens

Trigger: Context lost before buffer creation; many concurrent buffer allocations; VRAM exhaustion.

Common situations: Long-running or concurrent renders leaking GL buffers; constrained CI/Lambda; suspended tabs.
