Unity7 avoids 90% of the problem and is usually smooth resizing the same Qt apps. Although 10% of the time the bug is still visible in Unity7 too.
So there are two problems:
1. Qt apps resize much more poorly than non-Qt apps (just Ubuntu Qt apps??)
2. Unity7 resizing any window is much smoother than Unity8 resizing the same app.
