Here are performance measurements of OTA-9 and OTA-10's Unity8 spread animation on krillin. You can see the Unity8/QtMir render time has just about doubled, and the frame rate rougly halved:

The right edge switcher on both krillin and arale stutter when I drag it from the right edge and then swipe through the list of opened windows. This was not the case a few months ago, so we clearly regressed here.
