Presented videos contain images that are out-of-sync: bird's-eye view input with respect to reference driver overlay (blue box) and saliency map that are both generated after an episode ends.
This bug is caused by the fact that only last frame from stacked bird's-eye view input is drawn, but the rest operates since frame 0, hence the delay (4 frames, with skip of 4 = time horizon of 16 frames, gives ~1.5s delay).
