We trigger update_timers_and_animations() every time the event loop wakes up. If there's a real animation in the UI going on, that'll also trigger a request_redraw() call and all will be well. But when the only source of animation is set_has_active_animations() from RenderingMetricsCollector, then we might end up in a situation where the event loop is woken up before the rendered frame is on the screen, which means we invoke update_timers_and_animations(), but we won't render because the previous frame isn't shown yet. When it is shown and our presentation callback is invoked, has_active_animations() is false again. So instead, remember if we need to re-render once after rendering() and use that to decide if we need to re-render in the presentation callback. |
