Nested fullscreen interval 0 clients in Mir 0.25.0 had higher latency than interval 1 nested fullscreen clients.

I've reproduced this a couple of times and it is concerning:
   Interval 0: 81ms
   Interval 1: 64ms

Although this regression appears to be resolved in the 0.26 series (lp:mir) it's serious enough that we should look into finding what the cause was so that Mir 0.25.1 can get the same fix.
