SF: wait instead of presenting early If SurfaceFlinger duration is configured to a larger value than the vsync period, there might be a chance that SF would present the frame too early, if its actual duration is much shorter than anticipating. To prevent this, we wait until the vsync occurs before calling to hwc::present.
