Interesting. I&#x27;ve never thought of it as a security issue. But it&#x27;s something that&#x27;s around since forever. I&#x27;ve seen old framebuffers containing stills from games or videos showing up when resizing OpenGL applications 15 years ago. Video cards don&#x27;t clear memory for the same reason nothing is ever deleted by default - it&#x27;s a waste of time.
