Jitter while screen recording with avconv

I've figured out how to record decent quality with avconv now, the problem that remains which I also have experienced with ffmpeg and recordmydesktop is that my desktop background keeps flickering through. I've disabled the desktop effects in Linux Mint 16 Petra, running Cinnamon. This is how it looks: How can I avoid this? Should I use another Desktop Environment like XFCE? The command I am using: $ avconv -f alsa -ac 2 -i plughw:2,0 -f x11grab -s 1920x1080 \ -r 30 -i :0.0 -acodec libvorbis -ar 44100 -vcodec huffyuv grab.avi
