Can't start full screen on Mac

[bloop]

Since upgrading to 6.0.10 on my Intel Mac, I can't start Live in full screen mode. I save a project in full screen, exit, and reload it. For a brief moment, it loads in full screen, but then a title bar appears on the window, and the whole thing shifts down by the height of the title bar. The menu bar and dock stay hidden, so it's halfway between windowed mode and full screen. I have to do option-F11 twice to toggle it back to proper full screen mode.
