Vertical scrolling in programs like Zim Desktop Wiki or LibreOffice gets choppy, when some additional programs like Firefox are opened.
I assume, that it might has to do something with RAM. The choppy scrolling occurs only, when approximatelly 770 MB or more of my 2 GB RAM are used. Everything below and the scrolling is smooth again.

Using Ubuntu 12.04 64-bit with Gnome-Shell.
Any idea how to have smooth scrolling all the time?
