I have recently enabled compiz on Ubuntu 11.04 , everything works well except an annoying problem!
the windows title doesn't change , imagine you have many open tabs in firefox and when you change tabs it doesn't change ! its for very where (like natilus,text editor & .. )
but if you resize that window , it changes the title ! mean it changes the window title if you resize the window .
tool-bar title is ok and changes normaly .
