I have been using Ubuntu for about 1 year now and I got a problem just two days ago. Suddenly I started experiencing a problem with the window borders (title bar with close, maximize, and minimize buttons).

The problem :

• The window borders disappear
• I run "gtk-window-decorator --replace"
• For like 20 seconds everything is back to normal
• But it again returns to the problem.

I searched over the Internet and found that my problem is similar to what is specified in this bug report: https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/814091

This bug report says that the "fix released". I updated everything using the Update Manager, but still the problem remains.

Can anyone let me know whether the problem is fixed? If yes, can you please let me know how to do it?

I have already tried normal replace/reset commands like

• unity --reset
• unity --replace
• compiz --replace

The "window borders" plugin is on in CCSM (CompizConfig Settings Manager) and it points to "gtk-window-decorator".

I use Ubuntu 11.10 on an Intel Core2Duo T6500 with AMD Mobility Radeon HD 4300 graphics card.

If you need more information, please let me know.
