Exactly. As mentioned, I think frame-set-background-mode does this.

I think part 2 happens as part of frame-set-background-mode, as I mentioned up-thread, and it makes sense to me. What this might mean is that if you don't want the effect the original recipe produces, you should call set-mouse-color again after set-background-color.

This is only true of some X systems, not those for which this code was initially designed. But I am currently not horribly disposed to debug the details of Emacs code when one of its maintainers is deliberately turning a deaf ear to very reasonable requests on my part. Namely, not merging a branch for another month or so, once I have had a chance to correct a number of its deficiencies.

Your argument makes sense, but even if we accept that as correct, there are multiple things wrong here. Why is there only two out of six different ways to change the background that actually causes this to happen? (Even though I think your argument is valid, I still don't share your opinon. I think this is unexpected behaviour from an X application. I have never seen any other application which modifies my mouse pointer colors. But I'll accept your premise for now.) Given that you are concerned about making things invisible, the current x_set_mouse_color *guarantees* that the border around the pointer becomes invisible. A much more sensible default for this would be to use the frame foreground color. Or pretty much *anything* else than the frame background. I hope we can agree that in my example image, the pointer which has not been modified by emacs is much preferrable, and the one which has been modified is verging on unusable. In a multi-monitor configuration with many windows open, I find myself losing track of the mouse pointer and having difficulty finding it again. On a side note, even a black (unmodified) pointer is still highly visible against a black frame background, as long as the contrasting border around it is still present.

I don't know why you are suddenly confused, because the description of the bug has not changed. I have simply located the exact parts of the code responsible for (one half of) the problem, i.e. the cause of the mouse pointer border color being set to the frame background color. Maybe my description of the issue I observe has not been clear enough. Since you have not seen it first-hand, I attach an image which illustrates the difference in mouse pointer caused by setting the emacs frame background via the --background argument. (I don't know how well image attachments work, if at all, on the mailing list, so I apologize if the image does not make it through. Please let me know if it doesn't reach you.) The pointer to the left is how it normally looks, when emacs has not modified it and the original Xorg pointer is still intact. As you can see it is very easily visible, even against a dark background, thanks to the border color. The pointer on the right is the result of setting the frame background color through the --background argument. As you can see the pointer is now much less visible, since the border around the pointer is the exact same color as the frame background. Note that in neither of the examples have I set any custom mouse color, so I would expect it to remain unchanged in both. After finding the code I pointed to in my previous message, I realized that this is in fact a two-part problem. Part 1 is that x_set_mouse_color incorrectly uses the background color of the current (or default?) frame as the color of the border/outline of the mouse pointer. This makes that border in effect become completely invisible when hovering over the emacs frame, which can make the mouse pointer very hard to see. Part 2 is that the act of setting a default frame background color causes x_set_mouse_color to even be called in the first place. The mouse color should obviously not be changed as a side effect of changing the frame background color. These are two very different things that has nothing to do with eachother. I have identified the cause of part 1, but I have not (yet) found the cause of part 2. --=-=-= Content-Type: image/png Content-Disposition: attachment; filename=pointers-sideby-side.png Content-Transfer-Encoding: base64 Content-Description: Mouse pointers side-by-side difference iVBORw0KGgoAAAANSUhEUgAAAJkAAAA5CAYAAAAlQIlUAAABhWlDQ1BJQ0MgcHJvZmlsZQAAKJF9 kT1Iw1AUhU9TpSIVQYuICGaoThZERcRJq1CECqFWaNXB5PUXmjQkKS6OgmvBwZ/FqoOLs64OroIg +APiLjgpukiJ9yWFFjFeeLyP8+45vHcfINRKTDXbxgBVs4xELCqm0qti4BU+DKEPPZiRmanPSVIc nvV1T91UdxGe5d33Z3VlsiYDfCLxLNMNi3iDeGrT0jnvE4dYQc4QnxOPGnRB4keuKy6/cc47LPDM kJFMzBOHiMV8CystzAqGSjxJHM6oGuULKZcznLc4q6UKa9yTvzCY1VaWuU5rEDEsYgkSRCiooIgS LERo10gxkaDzqId/wPFL5FLIVQQjxwLKUCE7fvA/+D1bMzcx7iYFo0D7i21/DAOBXaBete3vY9uu nwD+Z+BKa/rLNWD6k/RqUwsfAd3bwMV1U1P2gMsdoP9Jlw3Zkfy0hFwOeD+jb0oDvbdA55o7t8Y5 Th+AJM0qfgMcHAIjecpe93h3R+vc/u1pzO8Hu3pyxDbRuwAAAAAGYktHRAD/AP8A/6C9p5MAAAAJ cEhZcwAACxMAAAsTAQCanBgAAAAHdElNRQfpAR8WFgDMtuSGAAAAGXRFWHRDb21tZW50AENyZWF0 ZWQgd2l0aCBHSU1QV4EOFwAAAPBJREFUeNrt3DEOgzAQAEEu4jdQw/9LUjvvcSqTPpITyzfT0AJa nY0ExLIddYGOHm4BIkNkIDJEhshAZIgMRIbIEBmIDJEhMhAZIoN/RVbLtdRyufsi6ysi8oX2eopM aEKbck8mNJEJTWjzPF0KTWRCE9ockQlNZEIT2lfWkU6m1oQfs2/H9Je4jhBWRHym2H7mCMvT5Q8D 2897gqVYJtvkakcb//6BWRrnF6P81aeW6142UwXYJtnEAXrVhzyTrE2zNJt/kYHlEpGByBAZIgOR ITJEBiJDZCAyRIbIQGSIDJGByBAZiAyRITIQGSIjnTf5w0/9EgES6AAAAABJRU5ErkJggg== --=-=-=--

> Set a breakpoint on x_set_mouse_color, perhaps?
I don't think a breakpoint will be necessary, I just popped in and had a
look at x_set_mouse_color, and it shows quite clearly that it does
explicitly do what I experience.
First it sets mask_color to the frame background near the start of the
function:
unsigned long pixel = x_decode_color (f, arg, BLACK_PIX_DEFAULT (f));
unsigned long mask_color = FRAME_BACKGROUND_PIXEL (f);
Then a bit further down it does this:
XColor colors[2]; /* 0=foreground, 1=background */
colors[0].pixel = x->mouse_pixel;
colors[1].pixel = mask_color;
x_query_colors (f, colors, 2);
for (i = 0; i < mouse_cursor_max; i++)
XRecolorCursor (dpy, cursor_data.cursor[i], &colors[0], &colors[1]);
So it seems that x_set_mouse_color always sets the mouse pointer border
color to the frame background. However, the foreground color defaults to
BLACK_PIX_DEFAULT.
This makes reproducing the bug even simpler, as it can now be done
multiple times from within Emacs without having to restart and passing
arguments to it.
This sequence of commands will do the same thing as the reproduction
steps I gave in the first message:
(set-background-color "#ff0000")
(set-mouse-color "#000000")
(set-background-color "#000000")
Technically, the only line needed is the set-mouse-color one, but
changing the background before and after makes it easier to see.
A slightly different question is of course why it even calls
x_set_mouse_color on startup in the first place, when there is no custom
mouse color configured anywhere. The default behaviour should surely be
to not explicitly set the mouse color unless a color has been specified.

I observe the same behaviour there. Even if it was "window-manager specific" as you say, I think that is a backwards way of thinking about it. This is happening in a *minimal* configuration where Emacs is running directly under X. Having third-party programs hide the issue by taking control over the theming of the mouse pointer shouldn't be the base case here.

Sure I'll post it below. I'm posting the output as shown in emacs -Q, since the bug isn't related to anything from my config/installed packages. I don't think this is related to a specific build, since it looks like the bug has been present since at least 2018: https://github.com/ch11ng/exwm/issues/513 Something that might be relevant is that I don't use any desktop environment or login manager, but instead start my window manager directly using startx.

Thanks, but I cannot reproduce this with the latest emacs-30 branch.

Starting Emacs with the --background-color argument results in the contour
of the mouse pointer being set to that color when it is hovering over
Emacs.
This also happens if setting the background color through
default-frame-alist in early-init.el.
Setting the background color on startup through either
initial-frame-alist or window-system-default-frame-alist works as
expected, and does not change the mouse pointer.
Changing the background color of the frame at a later time, either by
calling set-background-color or by loading a theme does not change the
mouse pointer, whether that mouse pointer has already been modified by
Emacs during startup or not.
I am able to reproduce the behaviour in a clean Emacs using -Q.
The easiest way to reproduce is through this command:
emacs -Q --background-color "#ff0000" --eval '(set-background-color "#000000")'
The results of the above command will be an Emacs frame with a black
background, and the mouse pointer will have a red contour when hovering
over that frame.
