Hi, I'm getting ~30% CPU usage (as reported by Task Manager) for an empty application in release mode on Windows 10. The code is just the "event loop" example from the crate documentation; it doesn't matter which ControlFlow I use. I'm not moving the mouse or interacting with the window in any way.
