Code review comment for lp:~bruce.ma/ubiquity/support-hidpi-lp1382291

* changelog, please describe the bug that is attempted to be fixed, rather than "how" or "who"
* the proposed change is not suitable for inclusion, as non-main components attempt to be used
* the referenced bug report has nothing w.r.t. incorrect wallpaper rending, it's the ubiquity window size which is wrong
* the ubiquity task on the bug report is marked incomplete

It seems like unity-settings-daemon is the one that needs patching.
