well, I do not rembemer using ccsm with this Ubuntu installation that
happen in 2013 (you can check in the original bug report).
I did play with it in the past, when ccsm and compiz were new, but was like
2009 or 2010 and on different instllation and machine.

I actually installed ccsm when you asked for the screenshot.

Anyway maybe it is because I just upgrade from release to release since
13.04?

BTW, the fix worked, without even restarting anything. Great thanks! :)
