Ok. I reproduce with --no-site-file and clean ~/.emacs with only:

  (desktop-save-mode 1)

But one correction - I lay about "-q". Evaluation of (desktop-save-mode 1) in
non-startup stage works different. For example it doesn't read
~/.emacs.desktop file (or just doesn't rearrange frame geometry) and when I
leave Emacs - it prompt for place for .emacs.desktop. With --no-site-file and
above ~/.emacs I am not asked for savefile and bug reproduced.

Here X window properties for shaded Emacs:

  _NET_WM_NAME(UTF8_STRING) = "EMACS desktop.home.int: *unsent wide reply to Eli Zaretskii*"

I see difference in value:

  _NET_WM_STATE(ATOM) = _NET_WM_STATE_SHADED

vs:

  _NET_WM_STATE(ATOM) = _NET_WM_STATE_STICKY

Is desktop-save code incorrectly recognise _NET_WM_STATE_SHADED ?
