RM>  One interesting aspect is that apparently in neither case we are
RM>  notified that our frame gets hidden when switching desktops.

RM>  Please do the following:

RM>  - Try again with the latest patch I sent you.

RM>  - Send me a diff of your "emacs with bug" and your "emacs without bug".

1. for emacs without bug

Frame size history of #<frame *scratch* - GNU Emacs at linux-egwc 0x55627cc9d400>
x_make_frame_visible
set_window_configuration (4), MS=140x150 IH IV 

2. for patched emacs

Frame size history of #<frame *scratch* - GNU Emacs at linux-egwc 0x5580c551de00>
set_window_configuration (4), MS=140x150 IH IV

RM>  And, if possible, run the version "without bug" under GDB and post a
RM>  backtrace from a position where it produces the "x_make_frame_visible"
RM>  line, somewhere around here in xterm.c:

RM>      if (!FRAME_VISIBLE_P (f))
RM>        {
RM>  	if (CONSP (frame_size_history))
RM>  	  frame_size_history_plain
RM>  	    (f, build_string ("x_make_frame_visible"));

RM>  	x_wait_for_event (f, MapNotify);
RM>        }

RM>  I cannot imagine how Emacs can get there without producing any recorded
RM>  events before or after it so it would be very interesting to find out
RM>  how it got there in the first place.

This one?
