It looks like it's indeed not to source of your problem.  The first
thing to check is your setting for display-buffer-reuse-frames.

The separate displays may still matter in the end, because Emacs is also
designed to work in conditions where frames are displayed in fully independent
displays located in different places (one in the office and one at
home, say), so it sometimes considers "frames in another display" as
invisible, just like iconified frames (except they can't be deiconified).
