In Gnome 16.10 I cannot get smooth scrolling on the new LibreOffice Writer 5.2.2 It seems to scroll screen lengths instead of you know.. just scrolling. It was fine in gnome 16.04 This "scrolling" refers to using two fingers on the touchpad. It will do the same as pageup and pagedown, instead of line by line (like up and down arrows). I remember and would like it to function like the up and down arrows work.. to move line by line.

I experienced exactly the same. I solved the problem by replacing libreoffice-gtk3 with libreoffice-gtk2 package
