It will only work for fullboth.  With practically all window managers
that accept size hints you have to set 'frame-resize-pixelwise' to
non-nil to make maximized, fullheight and fullwidth work.  You don't
need it on Windows because that does not process size hints.

What is "F11 maximized"?  F11 is "fullboth" (it was called "fullscreen"
once).  "Self correct" will work only if the top left corner of the
frame has negative coordinates.  This holds only for fullboth frames.

Yes.  But you wanted to make F11 survive restarts without setting
'frame-resize-pixelwise'.
