dandrader: 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. ** Changed in: qtmir Status: Invalid => New ** Changed in: qtmir (Ubuntu) Status: Invalid => New ** Also affects: qtubuntu (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to unity8 in Ubuntu. https://bugs.launchpad.net/bugs/1540702 Title: While resizing Qt apps window contents jitter about erratically (including during animations) Status in QtMir: New Status in qtmir package in Ubuntu: New Status in qtubuntu package in Ubuntu: New Status in unity8 package in Ubuntu: Confirmed Bug description: Resizing a window (Scopes) the window contents jitter about erratically.
