Description
macOS has an unusual behavior that it will not wait for V-Blank when the window is not visible. That can happen e.g. when the window is minimized or it is entirely covered by another window. While the issue is limited to examples, it's still bad because the examples are how people learn to use this crate.

Research direction
Start by reproducing the high CPU usage with the examples on macOS while their windows are minimized or covered. Inspect the examples' rendering and frame-pacing behavior; done means hidden examples no longer consume excessive CPU while remaining usable when visible.
