The following steps reproduces the bug.
Start emacs with `emacs -Q`
M-x pixel-scroll-precision-mode
Scroll a large buffer, works great.
Click and drag to select a region in the buffer. Click somewhere else in
the buffer. to unselect it. Scrolling around will now randomly skip entire
pages after scrolling 4-5 lines. This makes the mode unusable.
Additional info:
This emacs version is built using the settings for the default Tumbleweed
install, but with emacs 30.0.50 and some different settings. (native comp
and treesit)
emacs-30.0.50.14776.d4ff1d74209-65.6.x86_64 from vendor obs://

I cannot reproduce this, FWIW. The effect of scrolling is the same
before and after selecting a region.
Perhaps this is one more effect of known (and not yet solved) issues
with native-compilation? My Emacs was build without it.

Given it's 100% reproducible on my build, I went ahead with some testing of
configuration options.
It seems related to PGTK. ./configure --with-pgtk has the bug whereas the
version without it does not. Given the warning message about using PGTK
with X11, I assume that this falls under the same umbrella, and that I
should go complain to the package builders.
Let me know if there's anything more to look at.

Thanks. It'd be important to know whether this problem also exists on
the emacs-29 branch (I'd guess it does), in which case its urgency
will go up significantly. Can someone please try this in a PGTK build
of the emacs-29 branch, and report back? TIA.

I can confirm that it's also present on the emacs-29 branch, with PGTK on
X11.

I've said this many times: we don't support using the PGTK build on X
Windows, due to the frankly abysmal quality of GDK's X11 backend.
Unless this also happens on Wayland or Broadway, I will close this bug.
Try a regular X configuration instead.

I am aware of this, as mentioned above. I agree we need someone on non-X11
PGTK to test this, otherwise this just falls outside of scope. My previous
post was simply to confirm that the problem on X11 + PGTK is also present
on emacs-29, which isn't surprising considering pixel-scroll.el has barely
changed since then.
Cheers,
Patrick
