Elara pulled up the CEF debugger. It was a cathedral of complexity—a dozen threads, shared textures, command buffers, and the dreaded OnPaint callback. The standard pipeline was simple: the web content renders to a shared memory region or a GPU texture, and the host application grabs that frame and slaps it onto a native window. cef frame render

Elara leaned back, the cold coffee finally tasting like victory. She hadn’t just patched a bug. She had rebuilt the bridge between two worlds—the dynamic, reckless pulse of the web and the steady, rhythmic heartbeat of the native machine. Nothing kills the jank
