Shape update significantly delayed, and doesn't occur when MIDI not playing

[DJLevel3]

As described in the title, there is a significant delay between when the animation frame is updated and when osci-render actually renders said frame. The issue is much more noticeable when using MIDI, as the last rendered frame "hangs around" for a moment before skipping ahead to the correct frame.

Video example

This is primarily visible at the very beginning and the midpoint, where the camera angle changes after some time not playing a note.
