I recently installed Kubuntu 14.04 and available updates. Then I got several broken packages. I've already asked an question to fix the broken packages.

Now I noticed that I lost some visual desktop effects such windows background transparency on drag, outer glow on windows edges, smooth movement on windows drag, etc. which I had before I installed updates (I'm not sure if it is related to update installation though). Please check the screen shot below (open image in new tab or window for larger view).

You may see that the app launcher and the chrome browser windows seem flatten unlike the picture in the browser (with blue outer glow windows). I'm not sure this is somehow related to the other question I mentioned above. I guess it would be related to a failure of graphic driver packages or desktop effects settings, etc.

However, Desktop Effects and Workspace Appearance seems having settings they should have for Translunecy, Window Drop-down Shadow, Active Window Glow. Here're their settings:

System Settings >> Workspace Appearance >> Windows Decoration >> Configure Decoration >> Shadows

System Settings >> Desktop Effects >> Translucency

Here is the output of sudo lshw -c video:

In System Settings >> Driver Manager, the option Using X.Org X server - AMD/ATI display driver wrapper from xserver-xorg-video-ati (Recommeded Driver) is selected. And I confirmed that no fglrx* is installed in my system.

I don't see any difference except color theme. However, all changes you describe come from either widget theme or window manager effects. Go to app launcher -> System Settings. There are two icons, Application Appearance and Desktop Effects, that encompass the whole topic. Keep an eye on those "Customize" buttons that tend to be unnoticable.
For example, Desktop Effects -> All Effects -> Translunecy -> Moving windows set transparency for moving windows.
Workspace Appearance -> Window Theme ->Oxygen -> Configure ->Advanced ->Shadows has settings for glow. By "Smooth moving" you mean either Wobbly Windows effect from All Effects or this bug.

    Does anything change on screen when you enable-disable compositing manager (Alt-Shift-F12 by default). May be it can't start? – Barafu Albino Feb 12 '15 at 7:12
  • Oh yes. Alt-Shift-F12 got it back. What is this configuration in System Settings? – Sithu Feb 12 '15 at 10:34
  • Desktop Effects -> General -> Enable at startup. – Barafu Albino Feb 12 '15 at 11:56
  • Unfortunately, it couldn't be enabled on startup. I got the error "20 desktop effects could not be loaded" and "List of effects which could not be loaded. For technical reasons it is not possible to determine all possible error causes. Desktop effect system is not running". – Sithu Feb 12 '15 at 14:18
