Bug ID: 4054
Summary: Scroll preferences have no effect
Classification: Unclassified
Product: Claws Mail
Version: GIT
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P3
Component: UI/Message View
Assignee: ***@lists.claws-mail.org
Reporter: ***@anchev.net

STR:

1. Turn on Preferences->Message View->Text Options->Smooth scroll and set it to
any number of pixels

2. Half page can be on or off

EXPECTED:

Scrolling should be smooth and if half page is turned on it should result in
half page scrolling.

ACTUAL:

Setting these preferences changes nothing. Scrolling is not smooth and is not
in half-pages.

[Tested in version 3.16.0git237]

Half-page scrolling does work, but only when pressing Space or Shift+Space.
PageUp/PageDown still scroll the whole page regardless of the setting. I have a
possible fix for that.

As for smooth scrolling, I think this option should be removed. It seems it's
been made nonfunctional by some GTK+ optimization somewhere in past few years,
and I don't see a way to make it working again.

FWIW, the half-page scrolling has been fixed for a while, with commit
