[tracking] video playback performance
We consistently see high, fluctuating power, cpu, and gpu usage when playing back video. This is a tracking bug for investigating and addressing the issue.
While the cost scales with frame size, past investigations have shown no improvement when we disable the decoder and pass blank frames. We suspect the problem is something to do with how we pass the data to the compositor, or how it's painted.
