Bug ID: 423988
Summary: Single keystroke scrolls more than a screenful
Product: gcompris
Version: git master
Platform: Compiled Sources
OS: Linux
Status: REPORTED
Severity: normal

Hello!
I'm using GCompris 0.97 Based on Qt 5.12.8 on Ubuntu 20.04 LTS.
How to reproduce:
1. Open The tangram puzzle game
2. Click `?`
3. Press down-arrow key once and you'll see that more than a screenful text
gets scrolled in one go thereby making it impossible to read the very first
line after a screenful as it gets scrolled.
The same can be reproduced by clicking "Down-arrow" icon instead of pressing
down-arrow keyboard key.
The same behavior happens with the Configuration settings.
The fix can be restricting the one keystroke scroll to half a screenful. Please
note that anything less than a screenful will work. Even one keystroke scrolls
exactly a screenful will work too, but we should avoid this as that makes
screen to be filled with completely new text leaving user wondering whether
they missed any text right after the text on previous screen. Good scrolling
unit is such that it scrolls a part of the screen in a single keystroke so that
after one keystroke there is still some text from previous screen assuring user
that they didn't miss anything.
Thanks!
