Bug Description

Weird shadow is rendered on apps that don't use a traditional window decoration. I've attached a screenshot of synapse as an example.

I think this was introduced by the new CSD implementation in Unity for Trusty.

This is probably the same bug, but I'm not 100% sure. The Kupfer window, which has round corners and no decorations, gets square corners with the new Unity decorations: http://i.imgur.com/7H1K4li.png

This bug was fixed in the package unity - 7.2.0+14.04.20140402-0ubuntu1

---------------
unity (7.2.0+14.04.20140402-0ubuntu1) trusty; urgency=medium

[ Stephen M. Webb ]
* Release 7.2.0.

  [ Marco Trevisan (Treviño) ]
  * CompizUtils: only shadow-decorate alpha windows that have full
    decorations as well Since alpha windows might have custom shapes,
    it's safer not to shadow-decorate them unless they don't provide,
    for sure, a full decoration. (LP: #1281825)
  * Panel, Decorations: draw the background under the text glyphs before
    the text itself (LP: #723167)
  * PanelMenuView: use panel style context for painting the panel title
    (LP: #1296866)
  * SpreadFilter: use launcher width, scale on HiDPI, match also
    application names Launcher Width is now considered in setting the
    offset of the scale filter (fixes padding when launcher is in
    autohide mode). The search bar is correctly scaled when in HiDPI
    mode. We use ApplicationManager and thus BAMF to match windows by
    their name or app name. (LP: #1281297)
