Bug ID: 45099
           Summary: SetWindowPlacement doesn't restore the normal position
                    correctly
           Product: Wine
           Version: 3.6
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: minor
          Priority: P2
         Component: user32
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

Consider an application which calls GetWindowPlacement() on its main window to
store its geometry on exit and SetWindowPlacement() on startup to restore the
previously stored values. If the window of such application is maximized on
exit, then the window is correctly restored to the maximized state during the
next run, but restoring this window, i.e. returning it to the normal,
unmaximized state, doesn't restore it to the previous position (although it
does restore its size).

Here are some excerpts from the logs I see with WINEDEBUG=win for the last
execution:

I.e. SetWindowPlacement() is passed the correct position (3440,1910
corresponding to the lower right corner), and even restoring it still uses the
same correct position, but then the window is somehow moved to the wrong
position (115,87) for some reason which I don't understand.

This is just a minor irritant, of course, but I'd still like to open this bug
just in case it's also simple to fix.
