I believe that i just found a temporary workaround.
Since the flickering seems to be caused by the automatic mode detection
on my non-connected VGA output, I used xrandr to force a mode on that
output.
I used the following commands
xrandr --newmode dummy 75.00 1280 1301 1333 1408 800 804 808
WARNING! The xrandr commands from my previous post must be adapted to
set a mode on a NON CONNECTED output. Specifying some incorrect
modelines on a connected output could damage your monitor.
