LibreOffice Writer Scrolling Bounces or goes to the opposite direction
Description of problem:
When I use LibreOffice writer or calc with a multi-pages document and I try to scroll down, it scrolls a little then bounces back again, and sometimes it doesn't go to the scrolling direction, it goes in reverse (always going to the top, I tried the opposite: to go the top so I can get to the bottom but this doesn't happen).
You may note also that the scrolling is interrupted by these bounces, so I can't scroll for a long time!
Scrolling using the scroll bar itself is working just fine.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Open a document with multi-pages content in Writer.
2. Try to scroll down.
The scroll bar bounces back a little bit, or goes entirely in the opposite direction (always to top).
Scrolling down goes down without interruption.
This is the GTK3 version under Xorg.
This issue happens under Wayland too but not the same. The reverse direction isn't under Wayland. The bounces are less and I can scroll a long time without bouncing. but the bouncing is still there.
I don't know the reason, but I'm guessing that LibreOffice is so sensitive for scrolling and maybe it detects a very small bounces of my touchpad, though this doesn't happen with other GTK3 apps like Firefox, GNOME Notes, GNOME Files... etc.
Two finger scroll I guess. At least I see behaviour like that when using that mode.
The issue occurs on both: Two finger scroll, and Edge scroll. I tried it now with the mouse scroll and it works as expected.
I've tried to use the updates-testing to download the new version of libreoffice-gtk but I couldn't find it. Waiting for it to be published.

I've tried the last update on testing and yes, it has fixed the issue of going to the opposite direction of scrolling. but it's still has the a small bouncing when I stop scrolling.
The scrolling in general is not smooth in comparison to other GTK3 apps: Firefox and Document Viewer.
I'll attach a video for comparison between LibreOffice and Document Viewer (Evince).

LibreOffice Writer VS Document Viewer (Evince)
This is a comparison between scrolling in LibreOffice Writer VS Document Viewer (Evince). Note that I use the same motion timing and distance but it differs in reaction. Note also that you will notice a small bounce when I stop scrolling in LibreOffice.
This is 2-finger touchpad motion, BTW.
libreoffice-22.214.171.124-1.fc23 has been pushed to the Fedora 23 stable repository. If problems still persist, please make note of it in this bug report.
