(Get the code!)
So it seems like the issue is a combination of:
1. Unity8 using a zero swap interval (somehow, by accident?)
2. Unity8 taking around 10ms to render each frame -> 100Hz
3. USC can only take one frame every 16.6ms (60Hz), so will drop half of what Unity8 produces.
This yields only 50Hz output to the screen, which is roughly only every second frame from Unity8 reaching the screen, on an interval that's out of phase with the screen. So that's the stuttering.
