Hi, when I start in -gui mode I see no windows, just empty white screen. The command line version is working and producing png files.

Just for reference issues like this has to do with running a window manager that does not support reparenting. Try running this before starting the application. 

export _JAVA_AWT_WM_NONREPARENTING=1
