Summary:
When launching an app that displays a window that happens to hide the title and has a toolbar and has an autosave name, it will keep growing on the Y axis every time you launch the app.

Steps to Reproduce:
1. Create a new Mac project
2. In AppDelegate.m, set self.window.titleVisibility = NSWindowTitleHidden; in awakeFromNib
3. Open MainMenu.XIB
4. Set an autosave name for the window
5. Drag a toolbar in the window
6. Run the app and close it right away.
7. Re-open the app.

Expected Results:
The window should be the same size as it was when the app was terminated.

Got Solution

I've just encountered this issue too and was looking for solution. The problem is that window size is restored by the system using -[NSWindow setFrameUsingName:] before titleVisibility is set. Solution: 1. Remove "Autosave Name" value in Interface Builder. 2. Set it in code right after setting titleVisibility using -[NSWindow setFrameAutosaveName:].
