Not a Unity8 bug. Qt apps are equally jittery in mir_proving_server. ** Changed in: unity8 (Ubuntu) Status: Confirmed => Invalid ** Changed in: canonical-devices-system-image Importance: Undecided => Medium -- You received this bug notification because you are a member of Ubuntu

I think the web browser's resizing is uniquely broken in ways not seen in other apps. It might be better to discuss browser resizing in bug 1585278 instead. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu.

[Bug 1540702] Re: While resizing Qt apps window contents jitter about erratically (including during animations)

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

This is how it looks when I start an app from SDK on desktop running 16.04 and resize it: https://youtu.be/qP0ZI28wtUg So basically there's no 'live' update, the window just 'jump' to a new size. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed

[Bug 1540702] Re: While resizing Qt apps window contents jitter about erratically (including during animations)

Does it look any better when you resize the same app in Unity 7? If not, I would say it's a problem in Qt, that it's not repositioning and resizing its internal items as fast/smoothly as expected in response to a window resize. -- You received this bug notification because you are a member of

[Bug 1540702] Re: While resizing Qt apps window contents jitter about erratically (including during animations)

Not sure if that will be any help with fixing the bug but I've noticed the problem is only with right and bottom border of an app window. The top and left are fine whatever side I start resizing from. Also it looks like the title bar does not stutter when resizing, just the rest of the window.
