Bug Description

Latency from client to screen is one frame higher under Unity8 than in nested demo servers.

While mirvanity is reporting around 50ms windowed under nested Mir demo servers, it can only achieve 66ms in Unity8 on the same machine with the same Mir release (0.26.1 prerelease).

Incomplete - can't reproduce. Just ran mirvanity on zesty with the final Mir 0.26.1 release and Unity8 is within a few milliseconds of the demo servers.
