Thanks for the tip! It was caused by window manager compositing. I'm
using Linux Mint Mate, with Marco window manager.. It is very light
and stable, and earlier versions had compositing disabled by default,
but this one had it enabled for some reason. :) I just disabled it
from the desktop settings GUI, and softhddevice works fine now.

I am actually already using yavdr testing ppa's to get most of my vdr
stuff, I don't like to compile everything myself. :)
