Summary: Chromium Browser restore button doesn't work
           Product: Wine
           Version: 1.3.28
          Platform: x86
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
        AssignedTo: [e-mail]

1. Download chromium from
http://build.chromium.org/f/chromium/snapshots/Win/95816/chrome-win32.zip
unpack chrome-win32.zip, cd to the directory.

2. start chrome.exe with --no-sandbox, works around Bug 21232

$ wine chrome.exe --no-sandbox

Notice that the chrome window is decorated by the Linux native window manager.
Is it a bug? On windows, chrome have no traditional "window bar".

Now there is two "Maximal" button: one is drawn by Linux native window manager,
the other is drawed by wine chrome browser it self.

3. Click on the "Maximal" button which is drawn by Linux native window manager,
then chrome browser switch to maximal mode as expect.

This time, the Linux native window bar is disappear.

4. Click on the "Restore" button of wine chrome browser. However it doesn't
work. Wine chrome switch to normal mode for a second, then switch back to
maximal mode automatically.

I use ubuntu 11.04 , with traditional gnome desktop, gnome 2.32.1 .

There is some ways to work around:
I. Instead of clicking on the native "Maximal" button in step 3, try to click
the wine chrome "Maximal" button, then everything works as expect.
II. Do not set "Allow the window manager to decorate the windows" in winecfg,
then everything works as expect.
III. Do not set "Allow the window manager to control the windows" in winecfg,
then everything works as expect.
