Do you have any idea ? I assume it's working now?

As `vertices` is a dynamic array, .sizeof will only give you the size of the array reference (size_t.sizeof * 2, note that .sizeof will always give you a compile-time constant in D). Change it to glBufferData(GL_ARRAY_BUFFER, vertices.length * GLfloat.sizeof, vertices.ptr, GL_STATIC_DRAW); and the data will be correctly copied into the buffer. Many thanks !
