Ubuntu 12.04LTS Bug - Close, minimize and Maximize button becomes invisible in GNOME

Recently, I faced this issue of application window not showing the top most bar - containing close, minimize and maximize button.

I was using Ubuntu 12.04 LTS with GNOME Desktop Theme. As usual the problem was with ccsm (CompizConfig Setup Manager).

All I had to do was to go to Application -> Settings ->Compizconfig Setup manager (just type ccsm on the shell.)

once that is done, unmark (if already marked) and then mark again the Effects -> Window manager tab.

Try opening a shell. I hope this time you see the close minimize and maximize buttons.
