"Use system title bar and borders" messes up Chromium integration with Unity

[Feathertail]

Binary package hint: unity

PROBLEM

Once "Use system title bar and borders" is checked, Chromium has a space about the height of the tab bar between it and either the Unity application menu or the bottom of the screen. It will be considered maximized, despite this space. There may be graphical anomalies such as compressed-looking tabs.

Unmaximizing Chromium at this point turns it into a detached window. Maximizing it again finally brings it in line with the Unity application menu, and makes it actually fill the screen.

Chromium will take up the wrong amount of space every time it is launched, and will need to be manually reset each time. Detaching a tab will also cause it to exhibit the "broken" behavior, even if the tab is positioned so as to be maximized.

HOW TO REPRODUCE

1. Launch Chromium.
2. Click the "wrench" menu icon.
3. Click "Preferences."
4. Select the "Personal Stuff" tab.
5. Select "Use system title bar and borders."
6. Watch Chromium exhibit the behavior described above, even when closed and relaunched.

EXPECTED BEHAVIOR

Chromium will integrate beautifully with Unity without any tweaking required. "Use system title bar and borders" will be checked by default, and will not break anything.

To clarify, you're saying the behavior is broken when "use system title bar" is off, correct?

http://code.google.com/p/chromium/issues/detail?id=75485 might be related

[Feathertail (feathertail-deactivatedaccount)]

No, the behavior is broken when "use system title bar" is on.

http://code.google.com/p/chromium/issues/detail?id=75485 describes what happens when it is turned off. This issue describes what happens when it is turned on.
