bug#57475: 29.0.50; Position problem with make-frame on Lucid build

[Stephen Berman]

On a Lucid build, make-frame appears to ignore the frame parameters
(left . 0) and (top . 0), when passed individually or together:

0. emacs -Q
1. M-: (progn (list (alist-get 'left (frame-parameters))
                    (alist-get 'top (frame-parameters))))
=> (938 351)
2. M-: (make-frame)
   M-: (progn (list (alist-get 'left (frame-parameters))
                    (alist-get 'top (frame-parameters))))
=> (938 350)
3. M-: (make-frame '((left . 0) (top . 0)))
   M-: (progn (list (alist-get 'left (frame-parameters))
                    (alist-get 'top (frame-parameters))))
=> (938 350)
4. M-: (make-frame '((left . 0)))
   M-: (progn (list (alist-get 'left (frame-parameters))
                    (alist-get 'top (frame-parameters))))
=> (938 350)
5. M-: (make-frame '((top . 0)))
   M-: (progn (list (alist-get 'left (frame-parameters))
                    (alist-get 'top (frame-parameters))))
=> (938 350)

If one or both of the `top' and `left' parameters has a non-zero value,
that value is correctly realized; if only one of these parameters is
passed with a non-zero value, the other parameter is realized as 0:

5. M-: (make-frame '((left . 1) (top . 1)))
   M-: (progn (list (alist-get 'left (frame-parameters))
                    (alist-get 'top (frame-parameters))))
=> (1 1)
6.  M-: (make-frame '((left . 1)))
   M-: (progn (list (alist-get 'left (frame-parameters))
                    (alist-get 'top (frame-parameters))))
=> (1 0)
7. M-: (make-frame '((top . 1)))
   M-: (progn (list (alist-get 'left (frame-parameters))
                    (alist-get 'top (frame-parameters))))
=> (0 1)

The Gtk3 and non-toolkit builds do not have these problems, and on the
Lucid build, modify-frame-parameters and set-frame-position also work
fine with a 0 value of these parameters.

Please show the value of running "xprop WM_NORMAL_HINTS", and then
clicking on the frame in question after the cursor changes to a
crosshair.

Here's the output immediately after executing emacs -Q:

WM_NORMAL_HINTS(WM_SIZE_HINTS):
		user specified size: 674 by 676
		program specified minimum size: 34 by 66
		program specified resize increment: 8 by 17
		program specified base size: 34 by 66
		window gravity: NorthWest

And here's the output immediately after evaluating
(make-frame '((left . 0) (top . 0))) in the new frame:

WM_NORMAL_HINTS(WM_SIZE_HINTS):
		user specified size: 658 by 650
		program specified minimum size: 34 by 66
		program specified resize increment: 8 by 17
		program specified base size: 34 by 66
		window gravity: NorthWest

Right, but I'm not such which frame you clicked here: the frame in which
you evaluated make-frame, or the frame that make-frame created?

Sorry for the unclarity, I meant I clicked the frame that make-frame
created.

I'm closing this bug then, thanks.
