Are you running PGTK? It's not present in the official pretests of Emacs 28, but several very irresponsible individuals are haphazardly merging the code from Emacs 29 into Emacs 28, and then distributing packages labeled "enhanced or "wayland" on platforms such as the AUR. If you're running X, don't use PGTK. Here's the problem in this specific case: GTK uses the X input extension to detect mouse wheel movement, which relies on keeping the mouse wheel "valuators" in synch with the X server, and calculating the difference between GTK's own record of the valuator values and the X server's reported values every time a valuator changes. This is made complicated by the fact that an X window does not get events to update the valuators unless it has the grab, or the mouse pointer is on top of it. So, every time the mouse enters a window, GTK marks the valuator as invalid, after which two consecutive wheel events are required before any more wheel movement will be recorded: one to obtain the current value of the valuator, and another one so that the distance the wheel has moved can be calculated. Selecting for input extension events results in the corresponding core event mask being deactivated on the window. Some very smart window managers select for core wheel events (which are just button events) on the WM frame window, or the root window, and since there is no core button event mask on the Emacs frame window when GTK is using the input extension, the button events representing wheel movement get propagated up to the frame (or root) window, and that causes a grab to be activated and then deactivated, generating incorrect entry events, which then cause GTK to invalidate its own record of the scroll valuators, and causes wheel movement to be ignored at random. The solution is to use the official build of Emacs 28, and to not use PGTK on X Windows if you want to run Emacs 29.

Thanks for the insightful answers. The issue was inde= ed PGTK, the official build of Emacs 28 works fine. I didn't realize th= at the version I used was not official, sorry.
However, the same = issue still exists in Emacs 29 on Wayland and X (tested on GNOME on both X = and Wayland, using emacs-git with PGTK from AUR, which compiles from develo= pment master branch), where PGTK is officially supported. Based on your res= ponses, it seems that this is a known issue, but I cannot find any correspo= nding bug report (I could have missed it though, I'm a bit clumsy with = GNU's bug report logs). Should this bug report be moved to Emacs versio= n 29? Or should I report the issue again for Emacs 29?

Well, it's free software, so people can do what they want.=C2=A0 But bu= gs in
these Frankenstein Emacs versions should be reported to the people that
distribute them, which in this case is Arch Linux.

So there doesn't seem to be anything to be done on the Emacs side here,=
and I'm therefore closing this bug report.

I have the same issue with two different mouses (Logitech MX= Master 3 and
a cheap off-brand mouse). My build is running Wayla= nd (tested with xeyes
and by disabling Xwayland on gnome via= gnome-shell --no-x11).

The PGTK build is not supported on X Windows even in Emacs 29.=C2=A0 It jus= t
doesn't work well enough.

On the other hand, I don't see why that would happen on Wayland.=C2=A0 = Do you
see a similar problem with a different mouse?=C2=A0 And can you verify that=
your build is actually running in Wayland and not Xwayland?

You should leave it as-is, I think.

On X however, Emacs now receives too many scroll events per scroll on certain mouses. On Logitech MX master 3, every mouse wheel scroll is registered as a double or triple scroll. I would guess this has something to do with its scroll wheel, since it has an electromagnetic scroll wheel. Such issues do not exists on Emacs 28 though, but I guess I could probably make it usable by binding triple scroll to normal scroll.

This makes scrolling behave as it should on Wayland. On X however= , Emacs now receives too many scroll events per scroll on certain mouses. O= n Logitech MX master 3, every mouse wheel scroll is registered as a double = or triple scroll. I would guess this has something to do with its scroll wh= eel, since it has an electromagnetic scroll wheel. Such issues do not exist= s on Emacs 28 though, but I guess I could probably make it usable by bindin= g triple scroll to normal scroll.

What happens if you set mwheel-coalesce-scroll-events to nil?
