UbuntuShape rendering broken after rotating device to landscape and back to portrait

[Olivier Tilloy]

Steps to reproduce: in any app that has a TextField, rotate the device to landscape, then back to portrait, and observe how the rendering of the TextField is pixelated/aliased.

This is particularly visible in the browser app, but can be observed e.g. in the messaging app too. I’m attaching a screenshot that shows the issue in the browser.

Could this issue be caused by the shell rotation feature that landed a couple of weeks ago?

[Loïc Molinari (loic.molinari)]

Yes, it could be related. If it affects other shape-based components it is definitely an UbuntuShape bug, otherwise it could be something else?

[Olivier Tilloy (osomon)]

Indeed, buttons also seem to be affected. This can be observed in the "about this phone" section of the system settings. I’m attaching a screenshot of how it looks after rotation.

Search textfield goes strange looking in the System Settings too after rotation from portrait to landscape and back to portrait - it's pixelated and has a dark inner shadow around the whole shape

Status changed to 'Confirmed' because the bug affects multiple users.

Isn’t this a duplicate of bug #1455567 ?

[Loïc Molinari (loic.molinari)]

Bug #1455567 was meant to work around the fact that the shell wasn't doing the rotation. It was just a content rotation done by the app. Now that the shell is doing the "right" thing, that work around is responsible for the aliasing we're seeing. I'm proposing a patch.
