Use BEGIN_IMPL_FRAME_DEADLINE_MODE_LATE for impl thread redraws if the main frame is fast. |
|||
Issue descriptionIn most cases where the impl thread needs to draw, we use BEGIN_IMPL_FRAME_DEADLINE_MODE_REGULAR mode [1] which takes a more aggressive deadline [2] for the frame. This increases the number of cases where we would prioritize impl thread latency over the main thread, even when the main thread could hit the deadline. We should look into using BEGIN_IMPL_FRAME_DEADLINE_MODE_LATE for these cases to use the original deadline in the frame args.
