Bug Description

$ adb shell system-image-cli --info
current build number: 23
device name: krillin
channel: ubuntu-touch/stable/bq-aquaris.en
last update: 2015-06-15 19:22:22
version version: 23
version ubuntu: 20150611.3
version device: 20150529-8e13c5f
version custom: 20150528-722-29-15-vivid

Steps to reproduce:-

1. Swipe down indicators
2. Rotation
3. Switch rotation lock _off_, that is "X"
4. Hold phone in portrait and navigate to the top of the apps scope

Observe normal icons

5. Rotate phone 90 degrees to landscape, pull the scope "down" (to the side) slightly to force a re-draw

Observe poor anti-aliasing around the ubuntu shapes.

Two screenshots attached.
device-2015-06-18-220419.png - portait
device-2015-06-18-220428.png - landscape

The effect is most noticable if you open both of the attachments full-size and switch between them.

The same problem on Meizu mx4 r1

This screenshot was took after my 1st boot on OTA-4

Launchers icon look having the same effect of this bug. You will note that screen rotation is locked (Not sure it is same bug then cancel screenlock "rule" or if it's another bug with same behavior)

I have found a similar rendering bug which may be the same problem, running OTA5 on krillin:

- Open browser in portrait mode
- rotate to landscape then back to portrait
- The "location" text field outline will become corrupted as per the attached screenshot.

 Also other Ubuntu shaped text entries suffer from this problem.

  * UbuntuShape - Added support drop shadow aspect support to UbuntuShapeOverlay
    Fixes LP: #1480197.
  * UbuntuShape - Removed content orientation work around.
    The shape was using a workaround to make it render correctly when the
    content orientation was not the native one. This was perfect for the
    OrientationHelper shipped with the toolkit but now that the Shell
    implements the rotation, this is not needed anymore and causes some
    rendering issues. Note that the shape will still needs to support
    correct rendering when rotated using the rotation property of the Item,
    but that is a different issue. Fixes LP: #1466656.
  * UbuntuShape - Added a DropShadow aspect. Fixes LP: #1478129.
