Comment 2 for bug 871081

I can confirm this is happening to me in 11.10 as well. I did not have this issue in 11.04. Just to add to this, the problem only seems to occur for new Chrome windows. I can fix it for a single window and then toggle in and out of full screen mode and it will continue to function correctly. As soon as I close the window and open a new one I am back to the same problem. Here are detailed instructions on how to repeat:

1. install chromium in Ubuntu 11.10 (sudo apt-get install chromium-browser)
2. open chromium (I keep a shortcut in my launchbar) and ensure that "Hide system title bar and use compact borders" is selected under preferences
3. double-click on the panel at the top of the screen to exit full screen mode
4. notice that there are now 2 sets of close/min/max buttons
5. right-click on the Chromium menu and select "Use System Title Bar and Borders"
6. right-click on the Chromium menu and deselect "Use System Title Bar and Borders"
7. toggle in and out of full screen mode as many times as you like -- it should remain in compact mode without any gnome buttons or borders
8. close Chromium
9. open a new window and double-click the panel at the top of the screen to exit full screen mode
10. verify that there are 2 sets of buttons again
