Found a way to get rid of the black rect. Turning BES (colorkeying)
allways on. Maybe thats an interaction with X11.
#if 1
// BES _on_
if (videoLayer)
{
DFBDisplayLayerConfig dlc;
fprintf (stderr, " turning BES _on_\n");
dlc.flags = DLCONF_OPTIONS;
dlc.options = DLOP_DST_COLORKEY;//DLOP_NONE;
try
{
videoLayer->SetConfiguration(dlc);
videoLayer->SetDstColorKey(COLORKEY);
}
catch (DFBException *ex)
{
fprintf (stderr,"[dfb] BES-_on_: action=%s, result=%s\n",
ex->GetAction(), ex->GetResult());
delete ex;
}
}
// BES _on_
#endif
