OK, sorry, I didn't see the mention of Unity8 (or kgunn) in the description. I should follow all the links in comments.
Adding QtMir as it might have a similar cause to lp:1497128.
I'm still unable to reproduce using miral-app - which suggests there are two problems:
1. the deprecated window management code in mir_proving_server 2. racy code in Unity8/QtMir
I still think that /1/ is low priority.
