Actually I found the issue, and although I'm not really sure how it can
happen on X11, there's a bug in our code and an easy fix. The thing is
that somehow we sometimes (I don't know how to start it, but I sometimes
see it after a while) get SMOOTH scroll events in addition to the
regular ones (although we don't ask for them on X11 -- but Scintilla
does on Wayland, so we should properly handle this anyway), and we
wrongly assume that "not down" means "up" (e.g. that there's only 2
kinds of events we can get), which is wrong for SMOOTH events.
See https://github.com/geany/geany/pull/1843
@Jérôme : could you check the above fix works for you?
Regards,
Colomban
