Hi Markus,
this is not on the artifacts but on the 1-pixel shift:

I suggested a fix for this, Markus. Did you try it?
Hi Morten,
sorry, I did not try (at time in Germany away from my data).
I have been looking at that code portion and was not sure
about it (the confusing index).
I will apply the bugfix now.

now I can't test it myself, though I would really like to get it going
again.But I have very little time to play with the installation process. How do
you get the socket-driver to work? Shouldn't there be a makesockets.sh
script included somewhere?
The socket driver is default and plug-and-play nowadays. Do
you face problems to get it running?
