On Libreoffice 4.3.X and earlier a lot of users post problems or freezes of scrolling inside Documents
This seems to be a bug inside Libreoffice and Cache Handling or 3D Handling to Intel HD
Solution: Add last ppa sources to the System to pull newest Version:
- Open Gnome Terminal / Console
- enter:
sudo add-apt-repository ppa:libreoffice/ppa && apt-get update && apt-get dist-upgrade -y
To pull last from PPA Source Tree and install Libre Office 4.4.X which i tested successful
