Yes, see also below.

(I'm not sure this is still appropriate for the bugtracker; if you still
want to help me, maybe we should continue off list, though it's also
fine with me to keep it on list.) I cannot tell in gdb when I'm in the
window with the mouse face highlighting. I tried to do what you
suggested; here's the abbreviated protocol, with my comments and
questions interspersed:
Breakpoint 3, Fdelete_other_windows_internal (window=141312565,
root=139227370)
at /data/steve/bzr/emacs/quickfixes/src/window.c:2569
2569 w = decode_any_window (window);
(gdb) p w
$8 = (struct window *) 0x84c70ea
Is this the window with the mouse face highlighting or the deleted
window?
(gdb) br redisplay_internal
Breakpoint 6 at 0x8084dee: file /data/steve/bzr/emacs/quickfixes/src/xdisp.c,
line 12669.
(gdb) c
Continuing.
Breakpoint 6, redisplay_internal ()
at /data/steve/bzr/emacs/quickfixes/src/xdisp.c:12669
12669 struct window *w = XWINDOW (selected_window);
(gdb) br update_window
Breakpoint 7 at 0x8059e53: file
/data/steve/bzr/emacs/quickfixes/src/dispnew.c, line 3547.
(gdb) c
Continuing.
Breakpoint 7, update_window (w=0x8711888, force_p=1)
at /data/steve/bzr/emacs/quickfixes/src/dispnew.c:3547
3547 struct glyph_matrix *desired_matrix = w->desired_matrix;
(gdb) n
[...]
3655 changed_p |= update_window_line (w, vpos,
(gdb) p w
$9 = (struct window *) 0x8711888
Or is this the window with the mouse face highlighting?
(gdb) p vpos
$10 = 0
(gdb) p mouse_face_overwritten_p
$11 = 0
The highlighted text (still visible in the Emacs window) is in line 2,
so why is mouse_face_overwritten_p already 0?
(gdb) c
Continuing.
Breakpoint 7, update_window (w=0x86c4230, force_p=1)
at /data/steve/bzr/emacs/quickfixes/src/dispnew.c:3547
3547 struct glyph_matrix *desired_matrix = w->desired_matrix;
(gdb) n
[...]
3655 changed_p |= update_window_line (w, vpos,
(gdb) p w
$12 = (struct window *) 0x86c4230
(gdb) p vpos
$13 = 0
(gdb) p mouse_face_overwritten_p
$14 = 0
Now we're on the first line of a third (which?) window...
(gdb) c
Continuing.
Breakpoint 7, update_window (w=0x86f0e48, force_p=1)
at /data/steve/bzr/emacs/quickfixes/src/dispnew.c:3547
3547 struct glyph_matrix *desired_matrix = w->desired_matrix;
(gdb) n
[...]
3655 changed_p |= update_window_line (w, vpos,
(gdb) p vpos
$15 = 0
(gdb) p mouse_face_overwritten_p
$16 = 0
Fourth window...
(gdb) c
Continuing.
At this point the highlighting vanished. Does that mean the fourth
window is the one that contained the highlighting?
Breakpoint 6, redisplay_internal ()
at /data/steve/bzr/emacs/quickfixes/src/xdisp.c:12669
12669 struct window *w = XWINDOW (selected_window);
I guess the four windows are the two vertically deployed windows (one of
which was deleted at the beginning) displaying the buffer in which I
typed "test" on line 2 + the window displaying the minibuffer + the root
window; is this right? Why do they all show mouse_face_overwritten_p =
0 at line 1 and how can I tell which one contained the highlighted text?
