• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description galilette 2009-07-06 03:20:53 UTC]

cf. http://sourceforge.net/tracker/index.php?func=detail&aid=2816361&group_id=163434&atid=827735

per upstream description:
"
This is a bugfix for bug #2792759 (crazy scrolling when pointer leaves the
scrollbar when xinput enabled with GTK+ 2.16).

The cause of the bug is a change in GTK+ behavior which now leads the
scrollbar to incorrectly process xinput events. (change in the code of
gtk_range_motion_notify() in gtk/gtkrange.c -- used to call
gdk_window_get_pointer() and now calls gdk_event_request_motions())
"

Reproducible: Always

Steps to Reproduce:
1. open some xournal file long enough to activate the scroll bar
2. drag the scroll bar with stylus
3. stray the stylus away from the scroll bar area while dragging

Actual Results:  
scroll bar together with document content jump like crazy

Expected Results:  
normal scroll bar dragging behavior

only for >=x11-libs/gtk+-2.16

Thanks for reporting this issue, and the fix as well! Assigning to maintainer.

GTK+-2.16.6 is going stable very soon(tm) now.
If there are serious troubles without this patch, please also consider quick-stabling a fixed revision, to work with the soon-to-be-stable gtk+-2.16.6 with the GtkRange motion handling change

I have bumped this in the tree. Let's get it stable after two weeks of testing.

or.. rather not, it crashes on PDF export.

Is fixed upstream since xournal-0.4.5
