Compiz does not work well

view full story

http://askubuntu.com – Well this is the first time I'm with Ubuntu. The problem is that after installing Compiz and extras, I can install the cube and some other elements. But there are problems with: 3d windows, Paint fire, and Water effect. 3d windows makes the cube unstable and the window effects do not work as the cube disappears. Paint fire and Water effect simply do not work. After reading and reading, I installed the proprietary drivers and checked 3D acceleration; everything is correct, but those Compiz effects still do not work. The card is an AMD ATI Radeon HD 7400 ~$ glxinfo | grep direct direct ren (HowTos)
