Dear pixel-scroller (Dear Po Lu),

The pixel-scroll-precision-mode maintains active region
and this behavior could be useful.

However at the same time, PSPM provides more than pixel scrolling.
Should this be provided as option? 

1. emacs -Q
2. Make region active
3. Scroll using mouse wheel
4. Then region is deactivated

5. M-x pixel-scroll-precision-mode
6. Make region active
7. Scroll using mouse wheel
8. Then region expands as scroll down and up

Are you soliciting an option for pixel-scroll-precision-mode to
deactivate the region when scrolling begins?

It took me several tries to understand your request, so please excuse me
if I didn't fully grok your request.

Dear Po Lu,

1. Yes.
2. Since Emacs -Q deactivates the region when scrolling,
   on the default, pixel-scroll-precision-mode deactivates region.
   With option, pixel-scroll-precision-mode maintains region.

I hope this message makes my request clearer.

[Message part 1 (text/plain, inline)]

I recently tried pixel-scroll-precision-mode and was very surprised that
the highlighted region expands when, rather than being deactivated as with
regular scrolling.  as an X11 user I frequently use my selection to copy
text implicitly. then when I scroll to paste somewhere else I am dismayed
to get a large chunk of my text pasted instead of my original highlight.

I would like to either have an option to disable this behavior, or remove
it to match with the regular scrolling behavior.

thanks,

Jamie

Po Lu, any comments or suggestions?

Ordinary scrolling does not deactivate the mark when t-m-m is enabled,
so far as I'm aware.  Are you certain that you observe the mark being
deactivated when scrolling moves point, and if lost-selection-mode is
enabled, what if it is turned off?

[Message part 1 (text/plain, inline)]

the mark is not deactivated. eg C-w will copy from the beginning of the
formerly selected text to the point. however the highlighted selection
disappears and the primary selection clipboard is not updated as the point
moves.

This can be observed with `emacs -Q --no-init-file`. I am not intentionally
enabling transient-mark-mode or lost-selection-mode.

$ emacs --version

I can reproduce this in Emacs 30, but not on the master branch of our
Git repository, which will eventually become Emacs 31.  So I'm
guessing this is already fixed for the next release.

No further comments in 2 weeks, so I'm now closing this bug.
