I get the same behaviors with this options:

Configured using:
 'configure --prefix=/home/ergo/.local/ --with-mailutils --with-json
 --with-x-toolkit=gtk3 --with-xft --with-modules --with-cairo
 --with-harfbuzz --with-native-compilation'

Actually the behavior seems to be fine in gui (scroll by 3), what
actually seems a bit inexact is the terminal behavior (scroll by 6).
