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:
