Extremely weird bug : when I uncheck Settings > General > Start Minimized and restart app, I literally loose the title bar (and close, minimize, full-screen buttons and naturally the ability to drag and move the Window)
If I check back "Start Minimized" and restart, all gets back to fine (at the slight exception that FC starts minimized, unwillingly in my standpoint

Thanks
(I use FC 810 x64 on Win10)
