const canvas = document.createElement('canvas');
const gl = canvas.getContext('webgl') || canvas.getContext('experimental-webgl');

// Check if WebGL is supported
if (gl) {
    const maxTextureSize = gl.getParameter(gl.MAX_TEXTURE_SIZE);
    console.log('Maximum texture size:', maxTextureSize);
} else {
    console.log('WebGL not supported');
}

While fixing this also replace SetSelectionLayer loop with Array.Fill(pixels, transparent);

Just reduced max to 8192 since the workaround doesn't seem to fix it properly
