I've seen this in a bunch of ways -- window resizing, moving a window between displays, even having one window with a titlebar and one without! Here's a video. You can see that this pref is "false", and various actions (screen moves, maximizing) cause the titlebar to reappear or disappear. http://www.youtube.com/watch?v=BBNcHMbdieA&hd=1
P5 because you have to flip this pref to see these bugs.
I suspect that as far as causes are concerned, this is a dupe of bug 930094. Mike, does that make sense? If not, it should at least be taken into account on that bug.
Summary: browser.tabs.drawInTitlebar pref is sometimes ignored → OSX: browser.tabs.drawInTitlebar pref is sometimes ignored
Yes, this is a dupe of bug 930094. Thanks for reporting, rnewman!
