Light leak shader compile failed: ${log ?? '(no log)'}

Error message

Light leak shader compile failed: ${log ?? '(no log)'}

What it means

Thrown by `compileShader()` in the light-leak effect when `gl.getShaderParameter(shader, gl.COMPILE_STATUS)` is false — the bundled GLSL (`LIGHT_LEAK_VS` / `LIGHT_LEAK_FS`) failed to compile, and the driver's info log is appended. Since the shaders are static and shipped with the package, a compile failure usually indicates a driver/GPU bug or a non-conformant WebGL2/GLSL ES 3.00 implementation.

Solutions

1. Update GPU driver, Chromium, and Remotion to latest.
2. Switch the headless renderer to a GPU-backed Chrome or newer swiftshader.
3. Capture the appended `log` and report it with driver/Chrome versions to the Remotion tracker.
4. Temporarily remove the `lightLeak()` effect to unblock rendering.

try {
  lightLeak({...})(...);
} catch (err) {
  if (/Light leak shader compile failed/.test(String(err))) {
    console.error('lightLeak() shader compile:', String(err));
  } else {
    throw err;
  }
}

When it happens

Trigger: GPU driver with incomplete GLSL ES 3.00 support; swiftshader/llvmpipe rejecting an instruction; Chromium regression; virtual display without WebGL2 backing.

Common situations: CI on software rasterizers; older mobile drivers; Chromium downgrade; containers without a GPU device.
