Hi:
I have this config:
(setq-default mouse-wheel-scroll-amount '(3 ;; No modifier
((control) . 6)
((meta) . hscroll)
;; Either Shift+mouse not text-scale work in terminal,
;; so put them together
((shift) . text-scale))
mouse-wheel-progressive-speed nil
mouse-scroll-delay 0)
And I have noticed that the scroll speed on xterm doubles the one in
gui: with 1 mouse wheel tick
on gui: the buffer scrolls 3 lines (seems correct with the config).
in xterm: (emacs -nw) it scrolls 6 lines.
Is this a known issue? I have a workaround for it, but maybe there is a
real issue to solve?

You seem to be using a PGTK build. Please see if you get different
behavior differently on a build with the regular X Windows support.
Thanks.
If you're using X, don't use PGTK. It lacks certain features, such as
drag and drop support, which will require a rewrite of the selection
handling code to use GDK selections instead of the GTK clipboard,
working `yank-media', and is known to cause many problems related to
input.
BTW, some of your configuration options are redundant or make no sense:
--with-wide-int does nothing on a 64-bit system, and --with-xft,
--with-cairo and --with-x-toolkit=gtk3 are ignored when PGTK is enabled.
You might want to correct them.

I get the same behaviors with this options:
Configured using:
'configure --prefix=/home/ergo/.local/ --with-mailutils --with-json
--with-x-toolkit=gtk3 --with-xft --with-modules --with-cairo
--with-harfbuzz --with-native-compilation'
Actually the behavior seems to be fine in gui (scroll by 3), what
actually seems a bit inexact is the terminal behavior (scroll by 6).

Did you try turning on xterm-mouse-mode?

What do you mean? This is with xterm mouse mode on...

I didn't notice that, sorry.
Unfortunately, that means that I don't really know what might be going
on.

I'm pretty sure now that this is related with the events...
With `emacs -nw` when I scroll 1 tick and `C-h l` I see:
```
ESC [ < 6 5 ; 8 0 ; 1 9 M <mouse-5> ;; mwheel-scroll
ESC [ < 6 5 ; 8 0 ; 1 9 M <mouse-5> ;; mwheel-scroll
C-h l ;; view-lossage
```
While for the same scroll on `emacs`
```
<down-mouse-5> <mouse-5> ;; mwheel-scroll
C-h l ;; view-lossage
```
This is not really a very accurate measurement... but maybe could help
someone with more knowledge to clarify?
After a while checking I found that the issue only happens for `emacs
-nw` on xterm. On alacrity, rxvt and gnome-terminal it seems to scroll
the correct amount (3).
So I can report the issue to xterm developer?

I think this is a bug in xterm-mouse-mode: IIRC (though this may be very
inaccurate) xterm sends an escape sequence both for a mouse button being
pressed and for one being released.
On X Windows, moving the scroll wheel will result in both a ButtonPress
and a ButtonRelease event for the appropriate scroll wheel button.
But I'm by no means an xterm expert, so this may very well be wrong.

I don't see that here, xterm always reports only one <mouse-4>/<mouse-5>
event per wheel step.

Hi:
I just confirmed with the developer that this is an issue/feature/limitation with xterm omit translation mouse wheel... So in spite of the problem is there, it is not in emacs side, so you may want to close this issue.
Best,
Ergus
