OK, I think I understand this now. Maybe.
The problem is that the unity8 nested server BufferStream has not been
assigned a frame_clock (doesn't know what monitor to sync to), so it's
defaulting to unthrottled behaviour even though the swap interval is 1.
This problem should probably occur with any nested server. However it
was not noticed in testing because it will only be perceptible if your
nested server is also slow enough that its rendering period aliases
visibly with the physical screen.
