Failed to create WebGL buffer
Error message
Failed to create WebGL buffer
What it means
Zigzag setup allocates a vertex buffer (gl.createBuffer) to upload the fullscreen-quad vertices; a null return means the GL context refused another buffer object, so the effect throws before configuring attributes. Like the other null-resource throws, it reflects a lost/limited GL context rather than any parameter.

Solutions
- Ensure the render browser exposes a working WebGL2 context that is not lost.
- Render with Remotion's bundled Chromium (CLI/Lambda) with the software GPU path enabled.
- Reduce concurrent WebGL contexts by rendering effects in fewer parallel compositions.
- Recover from webglcontextlost by unmounting and re-mounting the composition.
- Update GPU drivers / backend where allocation fails.
Defensive patterns
Strategy: try-catch
Validate before calling
const gl = document.createElement('canvas').getContext('webgl2');
const webglOk = gl != null && gl.createBuffer() != null && !gl.isContextLost(); Type guard
const canAllocateBuffer = (): boolean => {
const gl = document.createElement('canvas').getContext('webgl2');
return gl != null && !gl.isContextLost() && gl.createBuffer() != null;
}; Try / catch
try {
return <VideoEffects effects={[zigzag({colors: ['#ff0000', '#00ff00']})]} />;
} catch (err) {
if (err instanceof Error && err.message === 'Failed to create WebGL buffer') {
return <Video />;
}
throw err;
} Prevention
- Probe buffer allocation before mounting zigzag().
- Render with Remotion's bundled Chromium; do not disable the software GPU.
- Reduce concurrent WebGL effects to free buffer slots.
- Re-mount on webglcontextlost.
When it happens
Trigger: setupZigzag calls gl.createBuffer() and receives null on the first zigzag frame.
Common situations: Headless render farm without working GPU acceleration; long-running session leaking GL objects; many effects each holding their own context; VM/Remote-Desktop GPU forwarding dropping buffer allocation.
