Hey, thanks for your suggestions!
One step closer - there was an uninitialized variable within the
framebuffer code :)
Now I can run:
====

without freezing the device. But the display is only flickering but the
bg isn't changing.
Running the gtk2-app "gtkperf" (gtk2 linked against directfb) prints the
following:
