There is major annoyace regarding compiz and xfce4 - new windows always slide from the tip of the cursor, to the upper left corner of the screen and i can't find option in CSM to turn it off. I even turned off all plugins in windows menagment section,but there is no results regarding my problem.
I like them to appear in the middle,just like im used to.
Open ccsm, go to Window Management, check Place Windows, click on it and set Placement Mode to Centered.
Finally after week of configuring arch i can now normaly using my computer, since that was last thing to fix.
Glad you got it sorted!
