Yes, even at maximized screen. I already have the menubar not to be global but inside the window.
Try:
// Show the full path to files in the title bar.
// On OS X, this value is overridden in the platform specific settings, so
// you'll need to place this line in your user settings to override it.
"show_full_path": false,
We did not change anything related to OS integration between 3124 and 3126. If your issue fixed itself, it was likely something else causing the issue.
Although I have not had menubar issues with any other applications for a while, I reinstalled 3124 just to confirm the issue, and it was not there. So you are correct.
