Failed to create WebGL vertex array
Error message
Failed to create WebGL vertex array
What it means
Thrown by setupChromaticAberration() when gl.createVertexArray() returns null. The VAO holds the quad's vertex attribute bindings (aPos/aUv at locations 0/1); a null return means the context is lost/destroyed or out of VAO objects, so the draw path cannot be configured and setup aborts.

Solutions
- Reduce concurrent WebGL-using effects/compositions.
- Enable GPU acceleration in the browser.
- Recreate the effect on 'webglcontextrestored' after a loss.
- Update GPU drivers; verify VAO support via WebGL2.
- Use a GPU-enabled/higher-memory render instance.
Defensive patterns
Strategy: try-catch
Validate before calling
function probeWebGL2(): boolean {
try {
const c = document.createElement('canvas');
const gl = c.getContext('webgl2');
if (!gl) return false;
const vao = gl.createVertexArray();
const ok = !!vao;
if (vao) gl.deleteVertexArray(vao);
return ok && !gl.isContextLost();
} catch {
return false;
}
}
if (!probeWebGL2()) skipOrFallback(); Try / catch
try {
return <ChromaticAberration {...props} />;
} catch (err) {
if (/Failed to create WebGL vertex array/.test(String(err))) return <FallbackFrame />;
throw err;
} Prevention
- Reduce concurrent WebGL-using effects to stay within VAO budgets.
- Enable GPU acceleration.
- Recreate the effect after 'webglcontextrestored'.
- Update GPU drivers and verify VAO support.
When it happens
Trigger: setupChromaticAberration() calls gl.createVertexArray() at chromatic-aberration-runtime.ts:112 after program creation; it returns null and the guard at :113 throws.
Common situations: Lost/destroyed GL2 context, GPU process crash, many VAOs across live compositions, or software rendering under pressure.
