Hi Maik, If I use the command line to launch with the default 800x600 window and then use the gnome window maximize (i.e. click the square in upper right corner of the window), I get the distorted-aspect-ratio image filling the screen. I am running Fedora 7 with nvidia graphics, gnome window manager. What is your environment?
