Hi! I want to enable a new vertex attrib array to pass the texture index to my shader but when I want to do it, the driver crash!

if (vertexBuffer.getVertexCount() == 0) {
return;
}

{
if (!m_cache.glStatesSet)
resetGLStates();
// Apply the view
if (m_cache.viewChanged)
applyCurrentView();
if (states.blendMode != m_cache.lastBlendMode)
applyBlendMode(states.blendMode);
// Apply the texture
sf::Uint64 textureId = states.texture ? states.texture->getNativeHandle() : 0;
if (textureId != m_cache.lastTextureId)
applyTexture(states.texture);
// Apply the shader
if (states.shader)
applyShader(states.shader);

When I comment this line : glEnableVertexAttribArray(4) it works.
