Dot grid shader compile failed: ${log ?? '(no log)'}

Error message

Dot grid shader compile failed: ${log ?? '(no log)'}

What it means

Thrown by dot-grid's compileShader helper after gl.getShaderParameter returns a failed COMPILE_STATUS. The message embeds the GLSL info log from the driver. Because the vertex and fragment shaders are bundled constants, a compile failure almost always indicates a driver bug, a non-conformant WebGL2 implementation, or GLSL ES 3.00 unsupported on the device.

Solutions

1. Read the embedded info log to identify which GLSL line/feature the driver rejected.
2. Update GPU drivers and the browser; retry on a different device or browser.
3. For headless/CI, switch to a SwiftShader software renderer which has conformant GLSL ES 3.00 support.
4. If the log points to a genuine bug in the bundled shader, file a Remotion issue with the full log and GPU/driver details.

try {
  state = dotGrid().setup(canvas);
} catch (err) {
  if (err instanceof Error && /shader compile failed/i.test(err.message)) {
    console.error('Driver rejected dot-grid GLSL:', err.message);
    // fall back to a CSS / SVG dot grid, or skip the effect
  } else {
    throw err;
  }
}

When it happens

Trigger: The bundled DOT_GRID_VS or DOT_GRID_FS fails to compile on the user's GPU/driver. Typical of outdated mobile GPUs, virtualized GPUs, or buggy drivers that reject valid #version 300 es GLSL. The info log in the error message names the offending line/feature.

Common situations: Older Android GPUs with stale drivers; virtual machines with passthrough GL; remote desktops over RDP; browsers falling back to a software rasterizer that drops precision qualifiers; very old Intel integrated GPUs.
