Having the setting 'frame-resize-pixelwise' to t in place I don't see
any slight shrinkage in any of the cases at the time of ctwm restart.

After ctwm restart, in all cases of F11 fullscreen, zoom, zoom vertical,
and zoom horizontal, the ability to toggle to previous frame size is
lost.  What I there do is move the entire frame to one side, C-x 5 2 to
create a new frame of default size, C-x 5 0 to remove the windowframe
that is unable to toggle between fullscreen and previous size because of
ctwm restart.
